Thanks, Pat, and I'll await other comments/suggestions from all of the
knowledgeable G5RV experts out there!
One thing I can also say, which I forgot in my initial post, is that the
G5RV is way way quieter than the screw-driver ever was. That does not
surprise me, since it's a horizontal wire antenna, but it is much more
pleasant to listen to on the receive side of things.
