David, if you just run a vertical wire, which is what you'd have by putting
a wire inside a fiberglass pole, you'll have a monoband vertical. You could
do one for 40 meters, for example, that would be around 34 feet high, a
quarter wave on 40. I don't think that's what you want. Zerofive makes a
couple of flag pole verticals, one for 10 through 80 meters, and a shorter
one for 6 through 40 meters. They're expensive though. Can't you put up
something like their 29 foot vertical, or can't you put up any vertical at
all unless it's a flag pole?

Hello Gary:
This idea is interesting, but I've a few questions:
How tall do you estimate this flagpole should be with wire placed inside(I
assume that it's a single length)to enable hf multiband operation(10-40
meters preferebly)?
Second, I've never dealt with so239 connectors before. How is it installed
at the pole base, and connected to the "hidden" antenna wire, and what is
its coax connector mate?
Lastly, am I correct in assuming that fiberglass doesn't resonate as well as
aluminum, and thus, it would restrict multi-band operation(even with use of
an indoor auto-tuner)?
Thanks for the advice, and 73.

David:
Another possibility is to get a fiberglass flag pole, and run a piece of =
#6 or 8 wire through the center.
Just drill a small hole in the side near the base, bring out the wire, =
put on an so239, affix it to the base.
insulated wire will work fine for radials.
get an edger, for burial or make landscape staples out of baling wire. =
just cut a piece about 6 inches long, bend into a narrow U shape.
Drive these down over your radials, the grass will root right over them.
