I had lost one local TV antenna channel due to weak or no signal some time ago. But when I lost a second one two weeks ago I thought I would try this amplifier. It worked! I got the first channel back and that second one fritzes out on me only occaisionally. So I'm happy with it.

I was disappointed at first"¦.then I read the directions. Initially had it set up between the tv and the cable. The directions said to place it closer to the antenna. I moved it and amazingly it worked! We live in the country and he antenna is blocked by several trees. We lost signal often before installing the booster.

I don't have time to go on and on about this, but very much want to share that amidst the dizzying array of questionable products from overseas offered, and questionable reviews, I managed to select this distribution amplifier and I am super happy with the purchase so far. It just worked out of the box for my application. Excellent quality, I hope it lasts.

I noticed a lot of confusion in the Q&A on Amazon for these types of products. I'll share quickly what I learned. I purchased an amplified antenna on here (https://www.amazon.com/gp/product/B09J1X2J3S), which also works great as a fixed pointing ATSC TV antenna on my roof. My wires all go to my basement, including all the coax to all the room outlets. So, the antenna control box and power injector must be at the other end of the cable from the roof in the basement. That powers the amplifier on the roof (this is a "Preamplifier", meant to amplify the weak signal off the air), which boosts and drives the signal through that long wire to my basement. The control box puts out a lovely TV signal, but that only works for a nearby TV. How, then to get that signal to all the TVs on the other ends of all the coax ends in the basement? That's where this product comes in--a "Distribution Amplifier". meant to take a strong signal and make it stronger so that it can push through a splitter (power divider) and then through more long cables through the house to all the TVs.

This product has one output, if you have more than one distant TV you need to run coax from this box to a splitter (1:2, 1:4, 1:8, etc.), and connect all the coax cables to the splitter. Don't use more gain in this product than you need. I find I need the max gain pushing through my 8:1 splitter and long cables.

That's it, good luck!

Most tv stations were weak and not stable. Right out of the box, this booster fixed the reception so the digital channels are stable and clear. I picked this one because it had several excellent reviews. I'm 45 miles away from the closest TV stations. It was set at the highest level of boost. After realignment of my antenna and using the TV signal meter. I was able to lower the output of the booster a quarter turn. I'm very pleased with how well this works.

I was staying in a temporary apartment that had poor signal on the TV in the room. This pre-amp did improve the signal to the point it was at least watchable but the signal at the input was too low to allow the big improvement I was looking for. The signal to noise ratio is the limiting factor ... you have to have at least some signal to allow the amp to work.
