Today I did a test mounting of the SDR’s discone antenna.
Yesterday, I received the heavy-duty 5-foot tripod and two 5-foot masts from Solid Signal. I did a test mount of the SDR’s discone antenna today with just one mast. It all fits. Now I need to get an antenna cable (15 feet of LMR-400, PL-259 to N male) for inside the mast and a weatherproof box to hold everything. Then all I have to do is run an Ethernet cable out to it and it’s up and running!
