Funciona muy bien lo compre ase unos meses y mejoro mucho la señal. Soy de área rural. De México compré otros amplificadores y no funcionaron bien. Solo este RCA es el que me funcionó perfecto

I read the bad reviews here and also online that the faulty power supply has been addressed. This inexpensive preamplifier exceeded my expectations. What you need to know is... 1) You can't amplify a signal your tiny antenna isn't receiving. 2) There are many factors involved in reception as in interference, overload, distance from transmitters, size of antenna, pointing, etc. 3) Make sure your power coax line is NOT split or interrupted when getting to the power supply 4) Make your splits after the power supply or you will not pass enough power to the unit. I have a 4 bay bowtie, LTE filter plus this preamplifier and it really solidified my reception. I recommend this, just make sure you read up on what antenna you need and how to install it properly. If your tiny $9 antenna doesn't sniff a channel at all, your preamplifier will not amplify a Zero signal. It can only amplify something received by the antenna and eliminate the loss of the coax run. It doesn't grant miracles. It works, just do your homework first.

Ok, some previous reviews were really negative towards this product. I purchased a 3 amp switcher power supply, in case the supplied wallwort quit. My findings after installation: RCA did a good job on designing a low cost/good performance preamp/booster. **NOTE**: The preamps sole job is to amplify tv signal so as to overcome feedline loss. I have replaced my coax as part of my install with a high quality flooded type Rg6 coax. So far I have not had any problem at all with my RCA preamp and it had outperformed the channel master spartan I took down that I had for years. This unit has a fm trap to help with close fm broadcast transmitters, which I did switch on. I cannot coment on its ability to handle overload strong nearby tv transmitters, as I am located in a extreme fringe reception area. Overall I think RCA did a pretty good job. (Don't over tighten coax to the connectors) (hand tighten is sufficient). It's a good product that I found so far. I will do an update review later probably 6 months-a year to give a full honest review. 73 GOD bless. K5EWM. UPDATE,: RCA has done an amazing job in bringing an affordable/guallity product for consumers. Mine has been up now over 2 months and has performed flawlessly. I did puchase a replacement wallwort power supply @ 12 volts 3 amp capacity (switcher) to operate it should it fail. The supplied power supply is still going strong. When I put mine up I used a coaxial discharge unit that is grounded with it's dedicated ground wire and ground rod. This is for lightning protection. The unit bleeds off the static charge that builds up and the spike energy from a close strike. If the lightning is super close it will blow out the discharge unit, but at the same time saving the preamp from damage. Amazon has these discharge units and they work very well. Now in a direct strike; there is nothing that can be done about that. It becomes a non functioning crispy critter. (Blitzed) (junk). RCA designed this product to operate on 12 volts via the injector and wallwort. Always use high quality coax feedline for less signal loss. I used a swept tested flooded Rg6 cable I made up off a spool (the good stuff). Being a flooded cable it doesn't assorb moisture leading to signal degrading and last a very long time. They said my cable was suitable for direct burial (not string trimmer proof) I didn't do that. RCA 👍 did a good job. Just don't over tighten the coax connectors/use good quality coax/ consider the use of antenna discharge units with ground rod & wire. Make certain when building a coax assembly feedline, be absolutely sure none of those small wires of the sheild can short the center conductor and blow out that wallwort power supply. Also very important; ( DO NOT LOCATE YOUR ANTENNA ANYWHERE NEAR POWER LINES) Let's be safe so we can enjoy all that wonderful free tv reception. Also it is a good thing to have a helper on an antenna project, and extra set of eyes to spot potential danger, and warn you of it and if a accident does happen they can call 911 if and when you can't. Be careful on ladders and roofs a fall from even a single story House roof can very well be fatal. Practice safety, it's for your own health and well being. Ok, I guess it's time to get off the soap box. Lol. Saftey-saftey-saftey in practice keeps you out of the hospital. 73 and GOD bless K5EWM. UPDATE: I made a mistake in my previous installation. With the outdoor portion amplifier mounted, I didn't leave enough slack in the input and output coax cables. I'm using a very stiff flooded version of RG6 swept tested 75 ohm coax. I used vinyl electric tape to secure both coax to the mast. Over time the taps shrank, much like heat shrink tubing. This caused extra pressure against both the coax fittings in the bottom side of the outdoor booster amp. That caused the fragile connections to break internally to the amplifier. This was my fault as I didn't leave enough slack, and was worried about wind vibration causing fatigue and then failure of the connections. I replaced both the power supply (indoor portion), and the outdoor amplifier portion, leaving more slack, so as not to repeat the same problem again. Anyone can make a mistake, including me. Lol. Tv reception fully restored and working great now. When I get time I will checkout the outdoor unit to see if I can repair it. If so, there will be more to come. These inexpensive preamp boosters work pretty good, considering the price point. Off air tv signals can be pretty complex in extreme deep fringe areas, like I'm in, so large antenna array are necessary to ensure satisfactory results. The boosters sole job is to help overcome signal loss of the coaxial feed line. Adding more amplifier gain, won't do much to get more channels. Bigger antennas or stacking for more gain is a much better route to improved signal. Hope this helps someone out. 73 Earnest K5EWM. Informational update: I have had good luck with this product and it works very well considering it's price tag. **NOTE**; for my install, I already had a good quality amplified splitter to distribute TV signal via RG6 to other rooms of the house. Typically most non-amplified splitters have horrible loss in signal and then the cable runs to each tv in the home. RCA has an inexpensive amplified splitter, using one of these instead of a non amplified splitter with killer signal loss can help out considerably to ensure you get signal sufficient to operate your tv and minimize signal loss in your multiple tv set installation. The RCA distribution amplifier isn't the absolute best money can buy; but for consumers trying to achieve tv reception goals on a budget, it's probably a game changer. All tv booster/amplifiers do 1 thing only: ( amplify a weak signal to overcome signal loss in coax feed line run). All boosters/amplifiers do generate noise (distortion) in the process of amplification. Now the lower the noise and higher gain is to the better. RCA has put together products in their upper line that will do ok performance for most applications and do so on a reasonable budget. I am talking about their higher end tv antenna amplifier products only. To really benefit and get high performance, the antenna must gather enough useable signal on its own to start with. I started working with tv antennas and improving reception from age 12; I am 65 years of age now and held amateur radio operator license since 1976 to present. I try to convey my findings to give an honest review that anyone can understand and benefit from. Enough about me, I have tinkered with this stuff my whole life. Now about safety (yours); DO NOT LOCATE ANY ANTENNA OR MAST ANYWHERE REMOTELY CLOSE TO ANY POWER LINE EVER! NEVER EVER ATTEMPT TO DO AN OUTDOOR ANTENNA PROJECT WITHOUT A HELPER. IF THERE IS AN ACCIDENT; THE HELPER CAN CALL 911 FOR HELP IF YOU CAN'T. SAFETY IS NUMBER ONE PRIORITY AT ALL TIMES! BE ABSOLUTELY POSITIVE CLEAR THAT WHEN USING LADDERS, THE LADDER IS SECURE AND WILL NOT SLIDE/BECOME DISLODGED OR NOT LOCKED INTO PLACE. ALWAYS HAVE YOUR INSTALL BUDDY LOOK THINGS OVER BEFORE THE JOB STARTS. CARRY NECESSARY TOOLS WITH YOU IN YOUR POCKETS, SO YOU CAN SAFELY COMPLETE THE INSTALL. 73 and GOD bless Earnest K5EWM. New update after 3 years continuous service. This preamp booster amplifier is built by parent company that owns Audiovox. The model I have has the 12 volt switching wall watt power supply rated at 200 ma. I use the fm trap to eliminate strong signal overload from a newly added FM broadcast radio station with pep transmitter rf output of 30kw. My tv antenna installation is less than 1/4 mile from the FM broadcast radio station transmitter and the FM trap is working well. 73 Earnest K5EWM. UPDATE: ***************** 09/22/2024 MY CHANNEL MASTER EXTREME DEEP FRINGE DUAL BAND VHF/UHF preamp booster amplifier has died. It didn't take a lightning hit. It failed in good weather and not a cloud in the sky. It is an expensive booster too. I pulled out old reliable RCA and redo my connections and im watching tv again via tv antenna. Performance result is every bit as good (as far as I can tell, without measuring -dbm output). I get identical signal bar levels on tv display for each channel. Those high end boosters look great on paper and there are applications where some difference can be realized, but not in my installation. RCA has designed a pretty good product at a value pricepoint that favors the consumer well. The perfect tv preamp booster amplifier will never exist, but useful bang for the buck (RCA HAS IT DONE RIGHT). SAVE YOUR MONEY; BUY RCA. I had to climb 120 feet of tower to change out the Channel Master booster to reinstall the RCA. A preamp/booster sole job is to overcome download cable loss. That is all it can do. Yes you can buy better, will it make that huge of difference; (if you use quality coax); probably not. Your antenna captures the signal, use the best possible antenna, a good quality support mast, high quality rg6 coax with good quality connectors, and a good quality preamp booster and a good quality amplified splitter in the house for coax feedline runs to other rooms of your home. Once a tv channel signal is lost due to feedline loss; its gone. It can't be reanimated by a booster amplifier, no matter its cost. Thats why boosting the signal at the receiving antenna works best. This is probably the final chapter in my review and update of this product. Im happy with my RCA it works when the high dollar Channel Master booster amplifier kicked the bucket 🪣 and cost 1/3 the price too. Stay safe with your install. Outdoor antennas are not a 1 man job. Get help. I personally know a amateur radio operator that did the lone wolf antenna install by himself. He is now a silent key 🗝️ because of his bull headed decision to work on the roof and ladder by himself. {[( SILENT KEY = GRAVEYARD DEAD }]). It cost him his life. So he was an experienced ham radio operator with lots of outdoor antennas experience and he died by himself, because he didn't have a helper. [[{{(( DON'T MAKE THE SAME MISTAKE ]]}}))!!!!!! 73 GOD BLESS EARNEST K5EWM. 08/08/2025 UPDATE ………………… THE RCA TV ANTENNA BOOSTER AMPLIFIER IS STILL WORKING AND DOING ITS THING. LAST TIME I WAS UP THE TOWER, I ADDED ANTENNA DISCHARGE UNIT PRIOR TO THE INPUT CONNECTION ON THE RCA TV ANTENNA BOOSTER AMPLIFIER. THE DISCHARGE UNIT IS GROUNDED WITH ITS OWN DEDICATED GROUND WIRE AND GROUND ROD TO EARTH GROUND. I HAD A SPOOL OF AWG 14 SOLID COPPER WIRE AND I USED IT. NORMALLY FOR THAT MUCH WIRE RUN (LENGTH) ID USE AWG 12. BUT THIS APPEARS TO BE WORKING WELL ENOUGH. THE AMPLIFIERS SOLE PURPOSE IS TO AMPLIFIY OFF AIR TV ANTENNA SIGNALS RECIEVED BY THE ANTENNA TO COMPENSATE FOR SIGNAL LOSS IN THE COAX CABLE IN ROUTE TO YOUR TV. IF THE ANTENNA CANNOT RECIEVE A DECENT QUALITY AND AMOUT OF SIGNAL TO BE AMPLIFIED. THEN THE BOOSTER WILL HELP VERY LITTLE IF NOT AT ALL. THIS IS TRUE WITH ALL TV SIGNAL AMPLIFIER BOOSTERS. SOME HIGH END TV ANTENNA BOOSTER AMPLIFIERS ON THE MARKET DO THE JOB WITH LESS NOISE AND SLIGHTLY HIGHER GAIN FIGURES. BUT YOU PAY FOR THOSE LITTLE IMPROVEMENTS. IF YOU WANT MORE CHANNELS WITH MORE RELIABLE AND STABLE VIEWING. A BIGGER HIGHER GAIN ANTENNA IS THE WAY FOR SUCCESS. ANTENNA HEIGHT IS A HUGE FACTOR AS WELL. GETTING YOUR ANTENNA UP HIGH ENOUGH TO RECEIVE A TV SIGNAL IS VERY IMPORTANT, OTHERWISE YOU WILL RECEIVE NOTHING. USE A HIGH QUALITY RG-6 COAX WITH PROPERLY INSTALLED CONNECTORS. MOST PEOPLE USE A 4-5 SECTION PUSH UP TELESCOPING TV ANTENNA POLE, AND IN MOST APPLICATIONS THAT IS GOOD ENOUGH. BUT NOT ALL. I HAVE MY TV ANTENNA INSTALLED ON A ROHN 45 COMMERCIAL GRADE HEAVY DUTY TOWER AT 145 FEET UP THE TOWER. MY AMATEUR RADIO ANTENNAS ARE WELL ABOVE THAT. MY TOWER INSTALL IS PROPERLY GUYED AND GROUNDED AND RATED FOR 130 MPH WIND. MY ANTENNAS ARE NOT BUILT FOR THAT BUT THE TOWER IS. DEPENDING ON YOUR PROXIMITY TO ANY AIRPORT AND LOCAL LAWS AND RESTRICTIONS YOU COULD PUT UP TO 199 FEET OF TOWER/ANTENNA, TOTAL HIEGHT NOT TO EXCEED 199 FEET AND NOT BE REQUIRED TO USE LANDING LIGHTS TO ILLUMINATE THE TOWER TO APPROACHING AIRCRAFT. LOCAL LAWS DO APPLY AND MAY RESTRICT SUCH INSTALLATION. GREAT CARE MUST BE TAKEN TO SELECT A TOWER SITE AS SAFETY IS THE MOST IMPORTANT SINGLE CONSIDERATION. SAME THING APPLIES TO PUSH UP MAST INSTALLATION AS WELL. NO PERSON SHOULD EVER WORK ON ANY ANTENNA PROJECT BY THEMSELVES. SAFETY IS TO BE USED AS IT IS THE LAW. ALWAYS HAVE A HELPER ON THE GROUND, AS THEY CAN CALL FOR HELP IF NEEDED. THINK ABOUT THIS: NO ANTENNA PROJECT IS WORTH A LIFE. ALWAYS HAVE A HELPER ON THE GROUND. 73 GOD BLESS EARNEST K5EWM 🇺🇲👍. Update: 10\19\2025 It's still working and doing its job. I have noticed the price has gone up, just about double. It is still a good product, for the money. Let me explain this one more time so people become educated about tv signals. Your tv antenna is of primary importance as it gathers the wanted signals and sometimes the unwanted signals. It gathers signal. Now if it doesn't have enough gain to reliable deliver the channels you want, it doesn't matter how big and bad your tv booster signal amplifier is. The amplifier can only amplifiy what it recieves. Lousy signal into the booster equals lousy signal out to your tv. The booster amplifiers sole job is to boost signal so it can overcome signal loss down the coax line to your tv. Please use a good quality rg-6 or better coax including the feed from the antenna into the booster. If you have a nearby FM radio station close by, then turn on the FM trap, located on the outdoor portion of the booster assembly. { read and understand instructions that came with your RCA tv antenna dignal booster amplifier.}. You do need to use an antenna discharge unit prior to the signal input of the booster and it must be grounded for it to do its job. 14 awg is about as large ground wire the discharge unit will accept. I used solid core copper wire in 14 garage, and it works well as I don't have or need a tv rotor { more trouble)}. When your working on your tv antenna installation, have a buddy on the ground with a working phone, so if you fall, they can call 911 for help. I personally know of multiple amateur radio operators who didn't do this and as result are now (silent key) (GRAVEYARD DEAD). THEIR ANTENNA PROJECT MISHAP, COST THEM THEIR LIVES! Overconfidence is deadly! Get a reliable budy to help you out with any outdoor antenna job, as it's the safe and smart thing to do. I know we all gripe about high taxes but death is not an acceptable means to tax relief. My rca booster amp is still doing a good job. When it does finally fail, I have a new one in the box to replace it. Nothing electronic will last forever, it is the nature of decaying time on capacitors and such. I think I'll buy a couple more of these so when a failure happens I have it covered with exactly what I need. Also beat more price increase as the dollar shrinks. Can you buy a booster with higher specs? Yes absolutely; but it will only compensate for sugnal loss in your coax downlead cable. Will you get 6.9 trillion tv channels if you buy this? Answer Hell No. To get more channels you need more antenna and or higher elevation of the antenna to capture the signal you think you want, barring the stupid commercials. Lol Understanding what each component of an off air tv reception antenna system does, will help you to make good decisions about your tv reception antenna system. Weather has some nasty things that mess up tv reception (pixilization and the dreaded NO SIGNAL display. Moisture in the air can reflect radio and tv signals. If moisture goes abnormally high, then other channels can interfere with a particular tv channel signal you are watching. When that interference reaches a level the tv tuner cannot lock onto the signal, then the mayhem begins. This is a good quality product that for most people and installation will perform well. You will never live long enough to buy the perfect booster. This one is good enough for me. 73 GOD bless and make sure your safety buddy is alert and not asleep when your on the roof working on the antenna. Earnest k5ewm 🇺🇸👍.

I live in the East Bay of the San Francisco Bay Area. I'm about 26miles line of sight from Sutro Tower (NW of me) in SF, but some of the channels I want come off of Mission Peak area, 13mi to my SE. Being a bit in the middle I wasn't sure how to pick up both. I was able to get an old Channel Master CM 3016 UHF / VHF / FM HDTV Antenna - 45 Mile Range (CM3016) antenna from my brother, and purchased a Winegard DS-3000 J Pipe Mount for Antennas to mount it. In my home I have several rooms already wired with RG6 that run to a central TV box outside. My living room however does not run there as it's RG6 runs much shorter to the Dish Network Dish. I extended that cable to the central location where the CM3016 is mounted, and also one RG6 goes from the TV box to there as well, and all this is from a 4-way splitter up on the roof. This presents a couple of issues: 1) The main room has a short length and better signal off the antenna. 2) Therefore the other rooms which are getting, by way of a 2nd 4-way splitter, weaker signal. Since most 4-way splitters have about a 7db drop, my run to the TV box was -14db loss, plus some more loss due to the long 100'+ run there, and then the individual runs to each room. I was not able to get KQEH very well in the bedroom due to this issue, but was getting it fine downstairs. This station is coming in from Mission Peak area, but on the backside of my directional antenna. This is where the RCA TVPRAMP1R Preamplifier for Outdoor Antenna Performance Enhancement & Extension (use with ANT3038XR & ANT3036XR), Black comes in. I mounted it using the included hardware to the mast, and cut a few more cables using some double shielded RG6, Ideal 33-632 F Compression Tool , Brand New Ideal Video Coaxial Stripper Rg59/Rg6 , and PPC EX6XLPLUS RG-6 Quad Seal Outdoor/Indoor Compression Connector, (Pack of 50) + Qty 5: F-81 F-Type PPC CF81GHZC 3GHZ Coax Barrels Coupler . I put a new WINEGARD TV-2900 82-Channel Weatherproof Transformer onto the CM3016 as well. I set the FM- Trap to off since I want to use it for FM reception and most of the channels in my area are UHF anyways. I also set it to the combined setting since I don't have a separate VHF antenna. To properly pass the power from the power inserter from one of my rooms up to the preamp I switched out two 4-way splitters to a couple PcConnectTM F-Pin (Coax) Splitter, 4 way, 2 GHz 90dB, 1-DC Passing . These block power to 3 ports and allow it to pass up the one port where it's clearly marked. This could be a reason why some folks have had no results and given bad reviews. They may not know how to properly use the power inserter. I have the cables from the Preamp going into one of the 4-way splitters. One output from there goes to the TV box where the other 4-way splitter is. Another output goes to a another regular 4-way splitter near the first one. This one is used to attenuate the signal another 7db and then have two outputs that are short runes. One to the living room, and one to the Patio for FM reception on a receiver. Inside the main living room is another 2-way splitter. One feeds my HTPC with built in AVerMedia A188 HD Duet - Dual ATSC PCI-E TV Tuner for Windows Media Center . The other feeds a SiliconDust HDHomeRun PLUS 2-Tuner ATSC DLNA/UPnP HD Compatible Streaming Media Player, HDTC-2US . I put the power inserter into the gym/extra room were I have an older HDTV LCD up on the wall. I was able to get about 14 more channels vs without the Preamp. The KQEH that I really wanted and couldn't upstairs comes in super clear. I was afraid that living in such a OTA signal saturated area a preamp would make the the already strong signals too strong, and tried to over come this by making sure to get -14db of drop through two runs through splitters, and it looks like the combo is very effective. I get nearly full strength on all channels now. I'm very satisfied with this preamp.

Works great. This gave me about 10 more channels that I like which were always spotty. Note that the weather boots only work if you are making your own coax connections...if you buy a piece of coax with connections already attached, good luck getting the boot on. I warmed up the boots so they were pliable but still couldn't get them around the coax head...instead I opted to skip the boot installation. We will see how the connections look in a year or two...
