I have a 25 watt mobile backpack rig, with a roll up j-pole that I can hang from the side of the house for simplex. The plan is to put up a 10’ tall comet base station antenna in the attic just above the garage with coax running the the wall to a jack by the workbench to plug the radio into. I figured that running simplex on 1.25m would be pretty “un-congested” to say the least.
