Query: It works

I needed something that I could mount on my wakeboard tower. Unfortunately, the largest 'rail' type mount I could find is about 1 inch in diameter, but that is not Terk's fault. What is their fault is that it's size... it is large. Like mentioned below, I don't think they thought this through... there are very nice and compact marine antennas for Sirius radio, but not for us XM users... Sirius's antennas are small, compact and low profile. But, this does work. I use it in Colorado where I boat in the mountains and foot hills and have not had any problems with the reception. One more thought, the terminal that connects to my Roady XT cradle partially broke off. It still holds the connection (friction) but it does come out time to time. I am in contact with Terk to see if there is a solution, or if a bit of glue is in order.
