Channel Master TV Antenna PreAmp 1-1-Port TV Antenna Pre-Amplifier, Built-in LTE Filter, 17-30dB Gain, Compatible with Non-Amplified TV Antennas, Increases Signal Strength, Indoor/Outdoor

I am about 50 miles south of DC. I got 25 channels without the preamp, and 51 channels with the preamp. I am using a Mohu Sky antenna. I am very pleased with my increase in channels. Prior to installation, all of my channels were pixelated when it rained. I am curious if the preamp will correct this issue, as others have reported. I did use a shorter length of coaxial cable that I bought from Amazon, previously, to attach the antenna to the preamp. Otherwise, the box provided everything I needed for set up. For Channel Master: an internal diagram would be appreciated on the printed instructions. I did find one on their website.

Bought this to replace an older winegard amp that had died on me. This one worked way better than the old system. I only used the lower gain setting but I was able to more than double the signal strength on all the channels I checked with this system. Getting clear signals from channels I've never been able to before. Would highly recommend. Works like a champ and easy to install.

This PreAmp works great for my attic antenna. My cable run has 4 barrel connectors, 50' of RG59 cable, and 100' of RG6. VHF channels that were too weak for our Tablo to pickup before we installed this Preamp are now viewed with a very strong signal strength. No more pixel issues and power supply has enough voltage to drive the antenna through all the cable/barrel connectors.

This replaced a PreAmp that went bad during a storm. This one has the closest amplification to my old one plus with a built-in LTE Filter. This brought the signal strength up and able to receive most the channels I had before. I was having an issue with channels breaking up even on the strongest signal strength. There is a cell tower near by. I added my external LTE Filter back on and all channels came in clear with no breakups. It's been working great. The built-in LTE Filter seems useless and has no effect.

works as expected,easy install

Works great, allows me to get a 207MHz VHF station with my attic antenna. Don't use it on HIGH unless you have hundreds of feet of coax.

Prior to installing this preamp, I was getting 136 channels on my HDHomeRun. Not all 136 channels were watchable though. I'm roughly 35-50 miles away from the towers. Reception mapping tools online show my reception will be "fair" or "weak" on basically all channels. My antenna is a Range Xperts Long Range antenna. I have a relatively short cable run (about 25ft) inside to the HDHomeRun. First, I'll note you need an extra coax cable than what comes with this kit. It includes 1 coax cable, but since you need to use their powered splitter, it requires another cable. I had to order a new cable just to try this preamp. Anyway, I installed it as the instructions show and did a scan. I got 20 channels with high gain. I switched it to low gain and got around 40 channels. All the channels I tried with the preamp were glitchy, even the ones that were solid before. Side note: the LED indicator light is supposed to change from green (low gain) to red (high gain) but mine stayed green. I noticed another review that mentioned the same. I tried researching my issue and the only conclusion I came to was that this preamp adds too much gain to my signal and overwhelms the HDHomeRun tuner. This doesn't make a lot of sense since the signal strength is only "fair" for most channels. Maybe the definition of "fair" is too vague. It'd be helpful if the manufacturer specified the conditions when it's appropriate to use this preamp. Not only is it expensive, but it typically takes most people a lot of time to add or change their antenna setup considering when done right, they are high off the ground and not easily accessible. Based on other reviews, this preamp seems to work for the most part. However, it obviously didn't work for me and in fact, made my reception way worse. I wish other reviewers would list important details, like how far their towers are, their cabling setup, etc. I sent this back for a refund.

Works as advertised, stopped all channels glitching on problematic channels, installation was straight forward and easy although mounting the amplifier to the pole was somewhat confusing, make sure to read the instructions

This channel master amplifier was installed inside our farm house, in the middle of nowhere. Channels are tough to get with an antenna because of distance and our metal roofs. We could get some Channels but the digital channels would digitize a lot and some days, would not even come through. We purchased this product in hopes of picking up and maintaining channels. We found we couldn't get more channels but the clarity of our current channels blows us away. The channels are crystal clear now. Don't necessarily buy this product to get channels, buy it to clear your current digital channels to crystal clear ones, with no digitizing. This amplifier does work and I feel confident recommending it in Canada.

I have used Channel Master products for years and was never disappointed. Their antenna Pre-Amplifier exceeded my expectation. It brought in a couple more channels as the one I used before, which died of old age. It also improved the picture quality. Mechanically well made. Their price is slightly higher than the rest but definitely worth it. Something nice they could add: A couple of protective plastic cover sleeves to protect the coax RF connectors from the weather. The ones I found on line are a bit pricey for what they are. I used heat shrink tubing instead.

My Channel Master 7777 pre-amp gave up on me and I had to find a replacement. I ordered this one and was not disappointed. I got 25 channels with this pre-amp. I used to get 30 channels before but I believe it's due to low humidity. I like how this model has LEDs to indicate that it's receiving power so I don't have to guess if it's working or not. Recommended.

worked well. Increased range of antennae. Easy to install.

I purchased the Channel Master after I lost All My OTA Signals in Late March- I played with antenna and got 2-4 stations back but not consistently- Enquired what I needed to Boost my Signals and decided on the Channel Master as their Record showed it was consistent and a Very good product. I face the South and South east and I am on the first floor to make matters worse- Ottawa Towers are to the North and on the other side of the building. Received it and retired my old system -Wineguard Amp -- I use the Clearstream Antenna and it does the job--been on OTA since 2020-No more Cable Bills !!!
