Funny, I've seen no one recommend addition of a 1:1 choke balun
near the
antenna feedpoint. If RF is flowing back down the shield of his
feedline, that surely could cause some incorrect readings on SWR in
the shack, wouldn't it?

And, how well would rf flow back down the shield of
"buried 75 foot of RG213..." ? :-)



About as well as it flows up the center conductor, possibly. You
don't think that just because the cable is buried that RF flow on the
shield conductor is prevented, do you?
