    Works fine 'cept for HD transmissions which is kinda a problem. Had to upgrade to $50 groundbraker. No problems with shipping.

    I have a television, amateur radio, police scanner and FM broadcast radio connected to an audio mixer. I was experiencing a strong hum in the audio output. After researching this on the internet I discovered the hum could be coming from my cable TV feedline. Sure enough if I disconnected the coax cable going into the cable tv box the hum disappeared. I ordered this ground breaker and installed it on the back of the cable box and the hum is completely gone. There is no degredation in the cable tv audio or video. This device works great if you have audio hum caused by a ground imbalance on your incoming cable TV feedline.

    Worked perfect to remove ground hum from AV shipping as well!

    Excellent Ground Breaker!! The TV cable was making my Bravia Sony to cut on and off by itself. Comcast solution was to run it thru my VCR tuner. The ground breaker solved the problem in seconds that I been wrestling for months. Thanks so much for a great solution that cost nothing compared to my $3,000 TV.

    This solved the horrible feedback/grounding problem we were having with our subwoofer. Too bad we tried soo many other things first. This works great.

    Great result, stopped the hum and the price was very good, I'd looked at one made by Jensen and that was 4 times the price!!

    Great product at a great price - just what we needed.

    While this product is good in theory, it unfortunately filters out certain HD channels rendering this device useless for my setup. I have heard that there are higher quality ground-breakers that will not filter out HD channels and that one of those would likely be better for protection on a digital cable coax line.

    After the cable company did an apparently exhaustive survey within my home, they concluded the audio hum was from my TV and not their issue. So before I called in the TV repiar guy, I went online and ended up on a HDTV installers bulletin board. Someone there recommended the Xantech. I ordered one and in fact it worked - no hum. I think I'll have a conversation with the cable company. They charged me for a service call because they said it wasn't a cable issue.

    So when I bought my new 42" Plasma TV (ED, not HD!) I noticed some thick but light colored bars moving up the screen, and a thin but distracing hairline that followed it. I sort of assumed it was because of it being enhanced def rather than high def, or there was some bad cable in the mix of something; I'm no real home theatre geek and wasn't sure where to turn for help. So I went to a big box retail store and talked to a guy about it. He said "Oh yeah! Those are HUM BARS. This will take care of 'em" and hands me a $180 power strip specifically for "line cleaning". Well, I figured that when I had $180 burning a hole in my pocket I'd grab one and hope it worked. After a search for hum bars on Google brought me here I thought "$10 to solve my problem? Vs. $180?" I took a chance, a small one, and I am ENORMOUSLY PLEASED. This item is nothing more that a small length of coax cable with an extra "bit" to it. The bars - GONE. The distracting hairline - GONE. The picture now looks GORGEOUS, exactly the way it should. Thank you SMARTHOME!

    Excellent product

    I had very bad horizontal(purple)lines, humming and static noise on my new LCD-HD-TV. I installed it before the digital cable box Coaxial line-in and it worked like magic. I it made me very happy.
