I bought this because my XM did not get a good signal in the northeast corner of the house. This allowed me to get the antenna in the best possible location for a great signal. Much better deal than brick-and-mortar stores.

This extrender works very well and I notice no decrease in signal strength with this added to the antenna. It's supposed to have an mini-amp in the connector that feeds off a voltage source run through the antenna. So it's gotta be better than just adding cable. I'd buy it again.

Was thrilled to see the 50 foot XM extension cable. The cable that was included with our XM radio was way too short for our small house, I don't know why they didn't include a longer one in the kit.
We could not find any extension cables here in town so ordered it from Amazon and had it in a couple of days.

The wiring for the Delphi extension seems to be really well made. I saw another extension cord, and the wire was very thin and looked like it wouldn't hold up well...especially if you decided to mount the home antenna outside somewhere and have it content with the weather constantly.

I have my Roady 2 home kit in the basement bedroom, and I just ran the cord into a hole in the drop down ceiling, and put it above the ceiling tiles all the way to the stairwell where it gets perfection reception.

The wire is thick and strong, 50 ft is enough for most people, and the connections are well made...works with the Roady series as well as the Sky Fi.
