[time-nuts] Effects on GPS antenna performance due to installation proximity of second antenna

Sun Nov 24 00:07:15 UTC 2019

I would appreciate feedback on the question of the ill effects (if any) of mounting two GPS antennas in proximity to one another. I am intending to mount a 58532A L1 antenna and a L1/L2 antenna on the same mast on my roof separated by around 1-2 feet. I have attached a photo to show the intended installation.  (Mast is clamped into the right side aluminum channel.) My concern is “shading” of one antenna over the other.  Thanks for the consult.
