TV Antenna Amplifier, 25dB High Gain Signal Booster for Digital TV Antenna Indoor, Low Noise/Clears Up Pixelated Amplifier, Adjustable dB&Timer, USB Cable Power Supply (White)

It's not a cure-all for your antenna woes, but it does gain some channels for me, and clear up some channels than can come apart🤨.If you have a splitter in your antenna lead, put the little amp before it, which will require a small phone charger (USB). It needs enough of a signal in order to amplify, so when before the splitter, it lets it push through the best signal. PS: I'd imagine in most cases, you'll want to crank up the gain at the little dial on the side (mine came in the lowest position out of the box).

I bought it on a lark, not expecting much, and I kinda got what I expected. I simply wanted to boost a pair of weak stations. This is not a good selection for a preamplifier. Unfortunately, you need to pay up for a good one.The best thing I can say is that… it functions. Powers up. Stations come on. Basically everything that would happen if it wasn’t there.However… The stations that are weakest, the ones which you’d hope to boost, were actually weakened, and either dropped out or became heavily pixelated.Even the stronger stations, which did not really need any boosting for a quality image, did not see an appreciable boost in signal- the check was accomplished using an iView converter box, which shows me a signal strength as a percentage.Most stations were throwing up between 67% and 85%, and they hover around those numbers. That is, a station at the lower end may dip to 65% or spike to 71%, and they generally bounce around a little bit. So I measured a boost based on a base signal range without the device, and then with the device after a rescan, and attempting to adjust here and there, though that should not matter for the weak stations- the max amplification would be best.As I stated, there was no appreciable difference for any station, except that the two weakest stations dropped out or became pixelated. Why that was the case instead of them staying in the same range, I couldn’t say.Both are UHF stations, at roughly 30 and 50 miles from the source, so it’s not a case of being over amplified. My conclusion is simply that it does not work.

My 10 year old TiVo bolt stopped receiving channels except for a couple, on a hunch I figured the internal signal preamp may be going bad, I thought perhaps if I boost the signal externally right at the coax input to the TiVo it may help, this worked perfectly, all my channels are back, I like the fact that the gain is adjustable although it didn’t seem to matter how much gain I set it to so I just set it to the middle, I was afraid to get a fixed gain version as the gain may over power the input, I also like that it has cellular signal blocking built in. I have tried the ones where it is two parts with the preamp that goes on the antenna and the power injector from inside the house, before, but I actually lose channels with that one. As you can see by the picture I had tried to open the TiVo to see if I could find a loose connection or anything, I wish I would have tried this booster first. tg this worked because I have seen new TiVo bolts up to $500.

I am sure there are a lot of variables, so not sure just how to rate this one. It is very easy to install, and it has improved the reception on channels that I was having problems receiving. However, not really all that much of an improvement.

Must be installed as shown in diagram with wired F connector to TV otherwise weakens signal. Other than that it seems to give a few db boost. I am using before splitter which takes 3db and this makes it like it was before the splitter was added. I have trees between me and the signal and this works most of the time. I also put on a TV with a quad bowtie winegard antenna which goes in window and it made it functional when it wasn't before. To be clear small boost not a high boost amp but it does boost the signal somewhat. Maybe it's 25 db at some UHF frequencies but on average I would guess about 3-10 db. Seems to boost channel 9 the most. This only worked on UHF and some low power VHF signals dropped. These were all commercial preachers so that's OK. I have VHF/UHF directional antenna on top of house.I wish I could turn the filter on/off also the timer function is worthless.

WOWZERS! Went form 4 channels to 13.

I just need a copule of DB to get audio. This device does not help to improve the signal. I see the same thing with or without it.

Like the product. It brought in channel, but the usb cord is very thin and will not stand up to gravity over time.I bought 3 of these and the wires to the USB connector on the cord to the tv came apart on all amplifiers after a about a month just from hanging (gravity).Needs thicker chords and stronger connections.
