I’m in the final stages of getting my shack set up and I’ve got a plan for everything except antenna placement. I’ve got a tripod and a 10ft fence top rail to use as a mast, but I’ve now decided I want to set up an iGate/digipeater in addition to my “conversing” radio. I would like to place both antennas at the top of the mast but I’m not sure how far I should separate them to keep from interfering with one another. The idea I had in mind was to get some sort of T bracket at the top of the mast, run 2 short lengths of pipe outward and then 90 deg elbow to angle back up. Basically will look like a giant tuning fork. I’ve done some research and the main points I’ve read are 1) no less than 1/4 wavelength apart but also the more space the better. Obviously since I’m at the top of a mast I wanna keep this setup as small as possible…so at what point are there diminishing returns?
