Re: Sirius Radio
I've been using Sirius for a long long time. On many vehicles, some with aftermarket receivers and some with OEM receivers.
Out here where I live and drive, terrestrial repeaters pretty much don't enter into the equation. There ain't none. (well, I think there are some near the cities, but that isn't where most of my driving is)
Short version: S-band and foliage do not get along well.
One thing that I've gotten used to is that, when Spring rolls around and the trees start getting their foliage on, Sirius gets dicey. Not usually unusable, but kinda annoying. The WK2/RA4/Sirius seems to be a bit more affected than the WK Sirius.. but it isn't night and day.
The silver lining is when the Fall arrives.. I get to take drives with stunning color, then the leaves fall, and Sirius becomes rock solid!
