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

I live in a valley about 4 miles east of Lincoln NE and 50 miles Southwest of Omaha. I have tried a couple of amps that cost around $35 to $40 with very poor results. I finally gave up and spent the $100+ for this amp. What a difference! I have installed a three-antenna GE UltraPro array in my garage attic, two pointing towards Lincoln and one towards Omaha. I now get 4 and 5 bars out of 5 reception on the Lincoln antennas and a solid 2 out of 5 reception on the Omaha channels. Sweet!

I've been using a flat fractal-style TV antenna for my living room TV since about 2015 and it did a great job picking up local stations about 99% of the time. I later added a SiliconDust HD HomeRun into the mix so I could share the signal to all the TVs in the house via my Emby media server.Unfortunately, due to changes in the location of local broadcast towers, I had to locate the antenna in my living room in an annoying location for it to work properly. I purchased this amp and a 'matching' Channel Master STEALTHtenna (see my review on that product).I initially installed the booster in high-gain mode and went from 11 channels to 15! This was a great improvement - and it worked great... for a while.Fast forward to last week and I realized I couldn't tune in some of the local channels, but could still see some more distant ones. I pull out the iPhone and fire up "Signal GH" again and I see that the signal strength is 100% but my signal quality is really low. Since I've been working with TV antennas long enough, I see the problem and realize what an ID:10T I've been - and immediately proceed to flip the booster to low-gain mode.Now I get *25* channels many with 100% signal strength and near 100% signal quality. I can now see all the local repeaters that were interfering with the main signal. I also now receive several channels from over 100 miles away, past the local group of towers. I also now see a host of channels from about 65 miles away, picked up on the BACK side of the antenna. Of the 25 channels I can now see, about 17 are worth keeping in my channel lineup.So kids, the moral of the story: don't be like me and immediately assume that you need 30db of boost when 17db is plenty.-------------------------My notes on installation:Installation is a snap... assuming you've installed an outdoor antenna before. I mounted my new STEALTHtenna and pre-amp on the j-mount for my old satellite dish. (after removing the dish of course)I installed short (18-inch) pigtail cable between the antenna to the correct side of the pre-amp. Then connected the longer run to the indoors via a grounded lightning suppressor to the (included) power injector. The injector is powered by a USB adapter (cable and adapter included.)For the main run, I reused the high-quality quad-shielded RG6 I previously installed for my satellite dish. All terminations have good quality waterproof compression F connectors. I usually seal everything with waterproof tape for extra protection, but I couldn't find my roll of coax tape - so I may come back to that later if needed. Even the local cable companies never seem to use the tape anymore since THEY switched to waterproof connectors, so maybe I don't either.Using the included zip-ties, I attached the the pre-amp to the base of the j-pole below the antenna. I don't really like how it looks, so I may re-mount it later on - especially if I ultimately decide to install a taller mount or an extension pole.

I've been using the Channel Master Amplify for several years now, and it's hands down one of the best TV antenna preamplifiers out there. It has everything you'd want in a quality pre-amp: adjustable medium-to-high gain (17–30 dB), built-in LTE/5G/FM filtering to cut interference, and the flexibility of both power over coax and direct-connect power options.This preamp is designed exactly how a good one should be: it's meant to preserve and boost a good signal at the source, not magically create one from nothing. If your antenna isn't receiving a usable signal in the first place, no preamp—this one or any other—will fix that. The best a preamp can do is deliver to your TV the same signal quality your antenna is receiving at the source (e.g., if you connected your TV directly to the antenna outdoors).Some negative reviews here seem to misunderstand how preamps work. If someone installs this amp and still can’t get good results, the problem is likely the antenna or it's placement, not the amp. A negative review of this product only holds weight if the reviewer got clearly better results with a different brand amplifier—which I highly doubt in most cases, because physics is physics. This amp is top-tier in performance and features.For anyone who understands what a preamp can (and can’t) do, and installs it correctly (especially placing it close to the antenna), this is a fantastic piece of equipment. Highly recommended.

I ordered two amplifiers, this and one for $37. Both worked to amplify the antenna signal that I get, and I get 11 channels with that. However, I ran a 100' coax to an out building to hook to 2 TVs. The signal was so weak, that it was sporadic at best, thus the need for something to amplify the signal going out.This one worked fine, all channels viewable out there, BUT the other one did as well, and was only $37! It does not pay me to keep this one. However, if you are going to mount a unit outside, instead of inside like I did, I do think this is a better unit by a small margin.

Best preamp I ever used , pair it with rg 11 coax for less loss. Great upgrade for any antenna or to possibly make a less antenna more effective. We went from rg59 coax to rg11 and added this preamp and now our omnidirectional antenna almost matches our small directional with smaller coax and no preamp . When looking at 200 just for a rotor it was more reasonable to go with the best coax , pre amp and omnidirectional..
