Well, sure. I don't -think- Brett's coax shields are connected to
-ground-... just to each other.

I've seen RG-58 with PL-259's used as center-button mic connectors.
Just cut the center pin down some...

Maybe it's because that's the way -he- wanted to do it, at -his-
station? *shrug* I dunno...

That's all the room he had. I can relate.
A while back, Craig, I was messaging with Brett, and took the
opportunity to look him on on qrz.com, then loaded up Google Earth, and
looked at his lot. He's got trees, neighbors, is on a corner lot, but
it's not a big lot.... several other limiting stipulations are involved...

I've said the same thing. If you've got room for an inverted vee,
you've got room for a Delta Loop, and that's what I'm running on a 120'
x 60' city lot. Lucky me, the tower was installed in 1981 (thanks Dad)
and therefore 'grandfathered' for any antenna height restrictions. No
Neighborhood Association idiots around here, either.
I gotta say though... my 450 ohm ladder line runs from the back of my
tuner to the loop.
