Review on 🔊 High-performance Amplifier: Cable TV RF Broadband with 8dB Gain, Four Output, 5-1002Mhz - Includes Power Adapter by Andrew Young

I had a strange problem with my Xfinity service when using TIVO and a cable card. On some HD channels I saw pixelation and channel degradation to the point where it was impossible to watch. I thought it was my TIVO Bolt or even the cable card that Xfinity provides, but since the signal issue was only affecting certain channels, I figured it must be the incoming signal. So, as a last resort, before calling Xfinity (ugh), I decided to try this amp and install it where it enters my house. I also bought new 6 foot coax cable and some 75 ohm terminators to close all unused ports throughout the house and also on this amp. If you don't close empty ports, they can act like antennas and lead to more noise on the channels or even a visit from Comcast for broadcast. The FCC requires Comcast and other companies to prevent this because it can affect other users' systems. I decided that for a few bucks I would just buy a set of 5 terminators and close the unused ports to avoid problems and also get the job done right. They are simply screwed onto the coaxial port. nothing complicated. I removed my existing splitter and installed this amplifier (aka a splitter), a couple of terminators on unused ports, and connected the incoming Comcast cable and power adapter. This amp REQUIRES an OUTLET nearby as it is powered to handle less than ideal incoming signals from Comcast (or any other service you have). I've seen many posts about this issue from many people using different services, so this is NOT just a Comcast issue. Keep in mind that this will boost the INPUT SIGNAL to compensate for the signal loss, but WILL NOT FIX AN INPUT SIGNAL ALREADY POOR. . It will simply amplify whatever comes into your home. If the signal is weak or bad for other reasons, such as bad wiring from the entry box to your house, it probably won't do anything other than amplify the bad signal. As for our issue, it was certain HD channels during the evening hours when Comcast system usage was likely to be higher, and there was no indication that the signal coming into our home was consistently poor. Only for a few channels. I don't know if Comcast can do anything with a particular channel's signals or not, but I didn't want to bother with them if I could avoid it, as their involvement is always a headache and they rarely improve anything and often create problems in my experience. They always want to blame our cables or router or whatever and I can do the same as their techs to troubleshoot. In this case I seem to have found a solution thanks to other posts, so I wanted to describe my problem in detail. Ideally, it would be nice if customers could call Comcast and ask them to fix this, but in many posts I've seen their solution is to do the same. Install this amplifier, terminators, etc. to solve problems for customers. Of course they want to avoid running NEW OUTSIDE WIRING, digging up the yard etc and I'm sure most customers don't want that unless the wire is really bad, broken, cut etc. Then that's it worth it, but for the occasional problem of only pixeling on certain HD channels at certain times of the day, this seems to solve it. So far we haven't noticed any additional pixelation issues on problematic channels, and our HD channels are as sharp as ever. Again buy that amp, a set of 5 or 10 75 ohm terminators to mute all unused connections in your house (i.e. where there are wire connections in your rooms) as well as on the amp itself and make sure it there is an outlet for powering the amplifier. The best place is where it enters the house. Much luck!
