Review on πŸ”Š High-performance Amplifier: Cable TV RF Broadband with 8dB Gain, Four Output, 5-1002Mhz - Includes Power Adapter by Maurice Stavros

Revainrating 5 out of 5

Fixed my Xfinity pixel issue on some HD channels.

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 might be my TIVO Bolt or even the cable card that Xfinity provides, but since the signal issue was only affecting certain channels I figured that it must be an 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 unused ports, to avoid problems and also to get the job done properly. They are simply screwed onto the coaxial port. Nothing complicated. I removed my existing splitter and installed this amp (aka a splitter), some terminators for unused ports, and plugged in the Comcast input 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 everything that comes into your home. If the signal is weak or bad for other reasons, such as poor wiring from your entry box to your house, it probably won't do anything other than boost a bad signal. As for our issue, it was certain HD channels during the evening hours when Comcast usage was likely to be higher. system, and there was no indication that the signal coming into our home was consistently bad. 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 I've seen many posts suggest 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 CABLES, digging up the yard etc and I'm sure most customers don't want that unless the cable is really bad, broken, cut etc. Then it's worth trying but for the occasional problem, that only certain HD channels are pixelated at certain times of the day, this seems like a solution. So far we haven't noticed any additional pixelation issues on problematic channels. and our HD feeds are clearer than ever. Again, buy that amp, a set of 5 or 10 75 ohm terminators to connect to all unused connections in your house (i.e. where wire terminals are in your rooms) as well as on the amp itself and make sure a Socket is available to power the amplifier. The best place is where it enters the house. Much luck! to solve problems for customers. Of course they want to avoid running NEW OUTSIDE WIRE, digging up the yard etc and I'm sure most customers don't want that unless the cable is really bad, broken, cut, etc. Then it's worth it, but for the occasional problem of only certain HD channels getting pixelated at certain times of the day, this seems like a solution.

Pros
  • Four-port passive return path amplifier provides +7.5 dB gain per port. Reduces snow and eliminates image pixelation with digital cable, amplifies antenna signals (OTA) for transmission to multiple TVs. May improve cable modem performance. Can improve HDTV reception.
Cons
  • I don't remember but there was something
