Thanks everyone for the info.

From everything I have read it seems (at least in the States) one needs a southern exposure for the antenna to get good XM reception. I was looking at that system because they have a waterproof boom box that works with a couple of the XM receivers. I didn't see anything comparable in the Sirius line. I need it for use in an area that is open to the elements (but has a roof). I like the idea that it is self contained (portable), weather resistant and has a remote. A litle concerned that I don't have a good exposure for the XM. I suppose I might be able to get better reception with a longer antenna - could bring it down with the equipment just in case.
Just don't want to get it all down there and find out I have lousy reception.

I've had Sirius for 5 years at least. Have a Starmate now. Never loses signal. Not even during Dean.
I am using the small magnetic automotive mouse looking antenna.

Tincup, I bring my XM radio to A/C, plug it into my cd player and set the home antenna out on the veranda, works fine (unless I kick the antenna ) you should have no problem as long as you can pay with CC or bill it to a US address.

We have XM and it works fine. There are certain times of the year that the signal will fade out for a few hours. I don't believe this happens with Sirius.
