THE CIMPLE CO Antenna Amplifier, Digital TV Signal Booster, Adjustable Gain, 24 dB Distribution, NTSC, ATSC, FM, UHF, VHF, 1000 MHz, Includes RG6 Coaxial Cable

This Amplifier works as it should and increased the weaker signals from my antenna as well as the clarity of the picture.well worth it in my opinion. works much better than some of the other brands that I tried.

Works great, I live in a dead zone and have never had good reception. With this booster I’m picking up more channels than I knew where available. I live about 65 miles north of Atlanta.

I was using an 18dB amp that came with an external antenna, basic plastic thing, that seemed boastful at 18dB, it was pretty weak. Temporarily using this antenna indoors for testing as I set up my new house. Figuring if it can do well inside, it will almost certainly do better when I mount it high up outside. This amp being 6 dB more at 24dB did the trick for FM signal. Cleared up the bits of static in the signal right away and I picked up a couple stations that would not lock on stereo loud and clear. I have it cranked all the way, but when I backed it off a bit, signal was still good.Have not used this one yet for HDTV/Off air channels, but original amp actually handled this frequency segment well enough, it was more the FM Radio signals I was trying to boost. Radio signal can be tricky, radios with built in antennas placed upstairs in one corner of the house are all good, downstairs in the opposite corner...static, weak, won't grab some stations at all. I went around with a battery powered radio outside and inside and found the sweet spot locations, but it's really about the number of walls, etc. between the radio and the tower transmitter out there. I live in a more remote area now and am sort of old school, I like having good old FM radio available for NPR and any radio stations I can pick up. This did the trick. I'm using apps more on smart TV's for some stuff...still wanted good strong FM/TV antenna infrastructure at the ready. I'm considering adding a second amp in line to boost the heck out of the signal, probably don't not need it. Previous owner had satellite TV (shudder, ripped that out immediately), so in house cable distribution is all over the place in virtually every room. Will take advantage of this for TV/Radio now as it's any easy swap/add.Some negative reviews here had me scratching my head, sounded like they might have hooked it up wrong or have a weak antenna/poor placement? Or it could be defective I suppose, but there is not much to fail with this basic amp. This amp does appear to have every bit of the power described. I've tried it with a smaller window mount antenna and a large modular exterior antenna (again temporarily inside), both had good to great results respectively.General rules of thumb:-Place an amp as close to the antenna as possible, this can make a big difference. If you place it way down stream of long meandering wire runs and splitters, might not perform as well.-Some even mount the amp right to the antenna pole outside and run power to it or an amp is integrated in the antenna. If you are within about 20 feet to the amp from antenna, should be all good.-You can stack amps in line, to push that dB power up there, although I doubt most people will need this.-If you are using existing coaxial cable TV infrastructure (and you are using cable TV boxes still over smart TV apps), caution when loading up amps in line with it, generally it's fine to share signals here, but too much can interfere with one signal or the other. Plus if you have cable TV, you probably don't need an off air antenna for HDTV/Local channels anyway.-Survey around the house for best antenna placement.-Invest in a quality antenna, remote steerable ones are really cool for dialing this in.

Surprisingly found five less channels than the ten buck cheap amplifier that came with my indoor antenna. However, it still found 101 channels so I'm not really missing anything much and the ones it didn't find were probably not worth finding. Five stars regardless because the picture quality is excellent so it's really amping up the signals, and it was a simple, plug and play installation. And it looks built to last, too.

Does not work with a amplified antenna. Was hoping it would increase the signal strength when in fact it killed what I had to zero on my over the air digital antenna. This was not stated in the item description that it would not work with an amplified antenna.

I have a TV in a far off bedroom from the exterior antenna and the attic signal splitter so reception in this room was poor. I connected the booster amp directly to the TV and got way better reception. I do need to move it closer to the antenna and signal splitter up in the attic so it will improve reception elsewhere in the home. Easy to hook up everything is included.

OK, this review is primarily for FM reception, however I did test it out on a TV also. I have tested many of these devices. I always test under the same conditions of temperature, humidity, tropospheric ducting, etc. I always use the same indoor antenna and the same position. Here is how they all work: You need a strong signal to get reception. So - you ask - why do I need this then? That is a really great question. The answer is - I do not know. Keep in mind antennas are not digital. They just capture radio frequencies out of the air. The primary factors of reception - whether digital or analog - are the same. They are primarily line-of-sight, number of active elements and height above average terrain. My house is in a low spot, so I just do not have enough signal for these amplifiers to work. They absolutely will not take a weak signal and turn it into a strong signal. Which, I believe, is what many people actually want! Amplifier is probably a bad branding name for these devices. Perhaps a better name is "strong signal cleaner". Your money is probably better spent on height and elements of your antenna. In spite of all this explanation, this particular device works better than others I tested. But my analogy is that you have to know how the word is spelled in order to look it up in the dictionary (or Google). So, in this case - you have to have a strong signal in order to have the signal boosted, or "cleaned".
