Are you positive there are no locations at your apartment that can receive
GPS. I live in an apartment and can get suitable signals with hockey puck
antennas mounted on four-inch square ground planes placed in various
windows. The ground planes are horizontal. I thought about tilting the
ground planes, but too much thermal ground noise is received.
