It's possible that LO leakage from one is jamming the other. When doing mobile

Yes, I've seen this. On installations in the past, when we were putting up
dual GPS systems, we always put them at least

Well, I have two HP conical antennas 4 feet apart and just
below the roof level, with an elevation cutoff of 30 degrees
for the large and growing oak trees on 3 sides. Fifty feet
of RG-8 each connects to two Z3801A receivers.

Recently I've had need to operate with two GPS navigation systems in

each other, or at lease get them as far apart as practical on a car otherwise
they both seem to interfere with each other and I can lose
