    Just what I needed. And it works perfectly. Adding this to my cable line greatly reduces/eliminates pixelation. I'm glad I found this at Best Buy.

    I use this as my splitter. It added a slight boost in performance but nothing like a Channel master. It seems to negate the normal signal loss at a splitter but nothing more

    I ran an extension off my satellite box via coax to another room and added this signal booster and my picture looks as if I am actually using a box in that room, really great pic.!! you may also want to look at the terk remote extender, it allows you to change channels from a different room without having to be in front of the box.

    It helped me to get better image and signal quality, not as much I was expecting, but for the cost, a 30% increase reception wise is okay.

    I was receiving 14 stations through a Clearsstream 2V HDTV antenna when connected to one TV. After connecting a second TV I had some pixelation on a few channels. After adding this in place of the non-powered spliter the signals were great at both TVs. I have since added a Wingard DNA-200 amplifier and receive 18 channels.

    I kept having connection issues with my wifi. I tried the regular splitters but nothing worked. I saw this and thought what a better way to boost my signal than with power. I haven't had any problems since. I plan on buying another one to replace an older splitter.

    I haven’t had cable in a while and needed a splitter to connect everything. Although it was an Open Box item, the splitter worked perfectly.

    This Rocketfish Amplifier was super east to instal and really delivers a great amplification of my antenae signal. Having more than one line out is really handy for hooking up my sound system for great AM/FM reception as long as you have a compatible antenna.

    Went to outside HD antenna, which works well with a normal splitter and two tv’s, but I needed more hooked up and the signal from a normal splitter wasn’t strong enough for getting all channels. Once I installed the drop amp, all channels are on all tv’s and have clear uninterrupted picture.

    Mounted amplifier in the attic near antenna, plugged in power and antenna, then attached cable to the TV. Seems to work as advertised and other reviewers reported. One of the more troublesome stations has definitely improved, not perfect but much better.

    I dumped Uverse TV and live 45 miles south of Houston. I purchased an antenna but needed to split the signal for two tv's. No problems hooking it up and the signal is really good.

    Bought this for my Comcast Triple-Play setup with 3 TV cable connection and one cable connection to the Xfinity Modem/Router/Telco adapter. Bought it because I couldn't always receive all channels on all TV's. Hooked it up and everything began to work simultaneous throughout the house for the first time since moving in 10 months ago.
