Thanks, this is very helpful. Given the low cost of a j pole antenna, I was thinking the best alternative would be to remove the dish and the log periodic from the mount, connect a j pole and reuse the ground. I wasn’t sure if the coax would be reusable but it sounds like no.

My recently purchased house is situated on top of a small hill and has an antenna setup (from a former owner, no longer used) with both yagi and dish antennas at the apex of the roof. With no nearby homes or trees to interfere, I think this is an ideal spot for a GMRS repeater antenna but have to wonder if the existing antennas could be repurposed. This would be ideal since they are already grounded and coax is wired through the walls to locations where the repeater could be installed. From what I have read elsewhere, seems the answer is that I need to remove these and install something tuned for GMRS, but I know little about antenna theory so checking with this group.
