Just as an FYI, I live slightly to the north of the 49th parallel and my antenna can see GPS satellites down to a few degrees of the Horizon. On a more practical note, I've seen numerous GPS antennas mounted on south facing walls (with little or no view to the north) in various commercial settings. My thunderbolt also seems to work best when I mask out satellites below 30 degrees or so.

I think they are about 60 degree inclinations. By your description you must be in the northern hemisphere. If you can, set up your antenna so it can see to the south and don't worry if the view of the north is blocked because as you found there is nothing to see there. -- ===== Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
