[time-nuts] GPS Signal Strength Through Roof?

I have 3 antennas in my shack, upstairs. The attic is pretty high, so 
the antennas are still a good 10 to 12 feet below the tip of the roof, 
which is covered with shingles.

They work fine there, but worked very badly when they were at eye level 
in the same room, probably because of multipath. Moving them close to 
the ceiling was a remarkable improvement.

I have made supports for the two outdoor antennas I have (Symmetricom 
and Trimble) and I am waiting for a good opportunity to install them 
outside, but seeing how well they work inside (at least from a signal 
strength standpoint, if not multipath or view angle), I have lost some 
of my initial motivation....
