Features
- Includes: 1 TV antenna television amplifier and 1 RG6 coaxial cable.
- How It Works: This adjustable, up to a 24 dB gain, distribution amplifier is used to strengthen signal reception from your antenna to TV, providing high output capability with minimal distortion. Please Note: This product can only amplify existing strong signals. Please check that you are within range of a broadcasting location, and that your antenna is big enough to receive the signal.
- Compatible With: Indoor use with VHF / UHF / FM bands, ATSC, NTSC, FTA, and OTA (the amplifier should not be installed outdoors).
- Features: The amplifier features a solid metal housing, 2 built-in coax mounting ports, power indicator light, adjustable gain control, and return path (for CMTS and other signals).
- For Best Results: Maintain a reasonable minimum distance between the antenna, amplifier, and equipment; connect the amplifier to the antenna before adding splitters; and turn the gain knob all the way up before scanning for channels.

I don't understand how a quarter of these comments say that it's not working correct or it's not working right you have to understand there's an input and the output it comes in from your antenna on the input the output goes back to your TV or your FM stereo plain and simple. That being said I had a signal that I could barely hear on FM that was between a zero and a one the signal strength when I turn that sucker on and turned it up it went to five and I had the stereo light lit I love this little amplifier it works like it should it's awesome.... I would recommend this to anyone

TL/DR: I added this amplifier to boost the signal on a distant station with occasional pixelation and dropouts. At maximum gain, I could not receive the station at all. I Googled "what happens if an ota antenna has too strong an amplifier" on Microsoft Edge. The AI response indicated the signal can be too strong, which will cause the tuner to drop the station when it struggles to decode the signal. I reduced the gain to about the midpoint and improved the signal. It took a LOT of patience to adjust the gain for the best picture. As a side effect, I lost a group of low power stations in my area, but I rarely watched them anyway. The instructions with the amplifier do not have any information on optimizing the gain. Details: I am using an Antennas Direct ClearStream 4Max with a Silicon Dust HD HomeRun digital tuner for distributing the signal through the house on the Emby app. The majority of the stations in my area are southwest of my home, and there is a more distant station south-southeast that has pixelation and dropouts. I have the antenna pointed to favor the south-southeast station, since it will pick up the closer stations more easily. The HD HomeRun displays signal strength for each channel in the scan, and shows a maximum of 4 bars of different color for signal strength. The best signal will be green bars; yellow bars for a good signal; red bars for a weak signal. I was able to roughly tune the amplifier gain and rescan using the HD HomeRun bars as a guide. I got to 4 yellow bars on the most distant station; the closer stations were at 4 green bars. I then fine tuned the gain to minimize pixelation while watching the station. Some televisions show signal strength level for the stations, which could also be used for tuning. Adding an antenna amplifier is not plug-and-play. This was a time-consuming process, but worth it in the end.

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.
