Rated 3 out of 5Â by VolRath217 Not enough gain
As mentioned in another review, the website says it's a 22dB gain, but it's only 4.5dB according to the manual. I've got about 25 ft between the antenna and the amp then 3 outputs: 1 30', 1 50', and 1 30' to a splitter to a 6' and a 25'. This definately boosted the signal enough for more of the channels to start showing up (especially on the 25' leg off the 2nd splitter) but several stations had choppy sound and tiling even on the 30' leg whose channels come in crystal clear if it's directly connected to the antenna. I believe that if I was already in the situation of getting all the channels only with choppy sound and tiling that this would have remedied it, but in my situation I'm going to have to take it back and find one with a little more gain.
Also, since all of this is going on in the attic, I had to install an electrical outlet in the attic. Fortunately the cables all come together right beside the wires that run the light fixture in the attic and I just tapped into it, but it would have been an issue elsewhere.
I'm going to say that I would recommend it, but only if you need a very tiny amount of amplification.

Rated 5 out of 5Â by TonyZ Excellent product and great value
Most of the prior comments here, are from individuals who do not undertstand their transmission signal problems, or the purpose of this Amplifier. You have to have a good signal to begin with. No amount of amplification will help a bad signal. Ten times zero is still zero. So you have to correct the cause of your bad or no reception before any amp will work. As one knowledgable user already reported, this is a distribution Amp. It should be installed directly into, and at the incoming CATV or Antenna cable coming into the home. This Amp is designed to help a properly installed system, who's signals have weakened, due to long distribution runs. It will perform best, when installed at the start, and not at the end of those long runs. If the runs are real long, it may be necessary to buy a stronger and higher DB rated amp, or either install a 2nd Amp like this one further down the distribution line that branches into other areas. Bottom line, if a signal is bad, an Amp will only make it worse. Correct any bad wiring, and make sure you have a signal to amplify.

Rated 4 out of 5Â by EdTVK Excellent low-cost DISTRIBUTION Amplifier
This is a very good and inexpensive DISTRIBUTION AMP. "Worst Buy" sells the SAME amp for $30. Specifications are not listed on the packaging, but ARE stated in the instructions. Would be 5 stars if specs were on outside of package.
Amplifiers like this get poor reviews because the users do not understand the purpose and use of amplifiers.
Television signal amplifiers cannot and are not made to "suck in" weak signals. They are intended to overcome signal loss from splitters and long cable runs. That is why it is called a DISTRIBUTION AMPLIFIER. Passive (non-amplified) splitters can reduce the signal strength by 50% or more per split. A distribution amplifier makes up for this loss (and some extra).
People incorrectly believe that an amplifier can bring in a signal that was not received before. The truth is that the signal WAS there before. With normal loss through cable and splitters, the weak signal was weakened to a point it could not be received reliably by the tuner. Inserting an amplifier helps to keep the signal at a usable level.
However, if an already strong signal is amplified, it can overload the receiver, REDUCING the receiver's sensitivity. In addition to amplifying any noise interference in the signal, additional noise is introduced by amplification. Digital television is particularly sensitive to noise because it can affect the digital data.
TIP: A Pre-Amplifier goes on the mast at the antenna to keep the signal strong BEFORE it goes through long cable and/or splitters.
A Distribution Amplifier goes between the antenna or signal source to DISTRIBUTE the signal to multiple receivers.

Rated 1 out of 5Â by spatula Worse with it than without it
Switching from an ordinary splitter to this distribution amp actually *reduced* the signal strength, rather than improving it. And yes, I understand what a distribution amp is for; the idea is to be able to split a signal to multiple outputs without the loss of signal that comes from using a conventional passive splitter. Unfortunately, this unit does not do that; you get less signal out than in, the opposite of what it's supposed to do, and even less signal out than with a conventional splitter. Given the number of reports of exactly the same thing, either a lot of these units are defective, or the design itself is defective. I'd recommend against this thing.
Getting this thing out of the package requires destroying the package, unfortunately, making it really difficult / impossible to return, so I'm basically out $20.

Rated 5 out of 5Â by kerndt Works great!
I put a $100 antenna on my roof and was okay with the results. Being I was splitting the signal between two TV's with over a hundred feet of cable I bought this item. My signal strength went from 1 and 2 bars to 9 and 10! Plus a few more stations!
