Tom:
It really doesn't matter one little bit as the G5RV is a compromise antenna
by concept.
The original version by Lou Varney was an antenna system, not just the wire
part, which used a top, ladder line feed and L C tuning network.
That tuning network was to match the antenna to the output of the
transmitter, which in those days would have been a tune tank circuit and
hence a bit more forgiving than the modern solid state final ends.
The modern versions which are sold commercially are arguably not G5RV
technically speaking, usually a top, 300 ohm ribbon feeder of about 34 feet
going into coax. They should have a balun at this interface.
This system requires a tuner and my guess is that this would be adequate
enough to tune out the altered mis-match which lowering the ends of your
antenna would cause.

Subject: inverted V
I have a G5RV which I want to set up as an inverted V. I'll have the center
at
about 32ft or so. This is a full length (52ft for each leg) G5RV. I'm
wondering what will be the best angle to have the legs come down at. Is
there a
formula for figuring this out. I'm probably not going to be able to play
with
this much if at all so I need to take my best shot right off the bat.
Thanks for any suggestions.
Btw: this will be for hf work.
Tom
