Good ideas from both- thanks for the feedback. I think you guys are probably correct. With as short as these wavelengths are there could indeed be issues with the way the coax is connected. I could imagine that since the Ht antennas I’m testing are electrically short anyway it would magnify any issues with the coax connection.
I’ll try connecting the coax to only the BNC connector, and then see what I get from my dummy load. If the SWR drops to 1:1 then I’ll know that it was the way the dual connectors were attached that was causing an issue.
If that is successful, then I’ll experiment with other ways to get both connectors attached. If I can come up with something that would allow both to be present that would be great, but if not I can always just use adapters to test different antennas, as was suggested.
Thanks,
Brandon
