Ron: I'm not familar with the S9 antenna but It might just be slid into
several
feet of 2" PVC pipe and let the pipe carry the load of the flag.
Might want to top it off with a tolet bowl float painted gold for the final.
Just an idea from a few QST articles. Good luck with your antenna project.
I agree with you that there several flagpole kits available. We used one for
field day. The Red Cross has a 33 foot SS pole insulated from
ground via wooden supports. With a few radials, it worked great on 40!

I have an S9 antenna; picked it up last year and then plans changed. It's a
very nice antenna, but it is not structurally robust enough to masquerade as a
flag pole.
That aside, I think you missed my point.
Yes, there are several commercial flagpole antennas available. That is to say,
base loaded (for the most part) verticals that look like a flag pole.
Nor is is that hard to take a commercial flagpole and base-load it to act as a
vertical.
And there are many commercial fiberglass flag poles that can be acquired, for a
price. Running a wire through the center of one isn't very difficult. Putting
a tuner at the base isn't either. I've heard of more than a few hams who have
done this. Even a few who've used a commercial fiberglass light support, such
as those you find around parking lots.
But my point was... I don't know of any current amateur radio antenna
manufacturer who is making a fiberglass (or other non-conductive outside) flag
pole with a hidden internal wire antenna, that has place INSIDE at the base a
screwdriver-antenna type assembly, to make about as "stealthy" a remote tuned
hidden antennas as you can get. Considering the vast availability today of
screwdriver-style tunable inductors, it seems so obvious that I'm just a little
surprised that it hasn't happened.
Yet.

All that being said... I wonder why no one has marketed a flag pole antenna,
using a hollow fiberglass pole, a solid copper wire in the center, and the
equivalent of a screwdriver antenna (the rotating inductor) safely hidden
internally at the base. You'd think there'd be a market for this. But that
is probably a discussion for an antenna related forum... and I thank you for
permitting the distraction here...

I think it is a real shame that things have reached the point where we
hams have to put up these sneak antennas, as if we are doing something
illegal, or operating spy stations in enemy terretory.
The ham magazines just about every month run articles about hams who
are so happy with their hidden stealth antennas which I believe only
gives lawyers more evidence to use in court when they are going after
some poor ham who has dared to put up a decent antenna and his town is
going after him to get it down.
If you have a high profile dipole way up in the air and you are happy
and you wind up in court and the other side lays out all these
magazine articles about how this or that ham got WAS with his secret
night time telescoping antenna or hidden wire under his eaves, or
closet slinky and how he's just delighted working everything he can
hear, he's going to have a hard time convincing a non-technical judge
that those antennas are unsatisfactory and his high dipole, or quad,
or beam are really needed.
If a ham has to get by with a stealth antenna okay, but the magazines
(CQ, QST and Electric Radio as far as I know) ought not to portray
these antennas as highly satisfying.
my opinion and worth what you paid for it.
