Manfred & Roger -
Those jigs are great! I don't expect to do anything above HF, certainly not above the 2 meter band, so they're just right - for me, anyway.
And I use my -H and -F for hobby work - no need for professional accuracy, either.
I had done something similar to Roger's BNC/binding post idea, but much cruder.
Thanks so much for the contributions. This kind of stuff makes this group such a great place.
