* Flawless! ...

Sirius Extension Kiy
The extension cable was exactly what I was looking for. I hooked up the Sirius antenna with the cable that came with the unit, but it was way too short to extend on my roof. I have an adjacent building at five stories and was blocking the signal. The extension kit seems to be a higher-quality cable than what came with the original Sirius antenna. Very satisfied.

Works, No Trouble
I had zero connectivity prior to installing this antenna, now I have excellent reception. It runs from the stereo into the cold air return, through the crawl space, out a vent in the foundation, up the downspout, up to the peak of my roof. I did hide the connection under the eave and have had no trouble with it. I attached it to my ridge vent with liquid nail.

* worth buying ...
Plain and simple, the Extension kit was worth the money. We can now listen to Sirius all day long in the house without losing signal. We used to move anteanna around room and we would lose signal quickly.
Wish I bought it last year.
