Some more suggestions...
Talk to local lighting and riggers for touring stage shows. They use a lot
of lightweight aluminum truss and all sorts of nifty clamps/bolts/fixtures
that might be useful.
8" triangle truss is about 15 pounds for a 10 foot length in my vague
recollection. It would easily support several hundred pounds loading
axially, and perhaps a few tens of pounds wind load (unguyed) with 40 feet
bolted together.
Not cheap, though.. probably $100/stick used, twice that brand new.
Portable scaffolding is another alternative. Takes a bit of time to set up,
but quite rigid, and getting to 40 feet is no challenge. You could also
climb up there to fool with the antenna while standing on the floor of the
top level.
Anyway, take a trip down to your local rental yard and look around for
ideas. People have to hang things 40 feet up all the time.

Subject: [TowerTalk] Portable tower info
Our local amateur club is working on putting together a portable emergency
communications package that can be used in case of local emergency.
Everything has gone together very well except we are having problems putting
together some type of support for a HyGain TH-3 triband beam.
We are trying to keep the size of the entire communications package down to
where it will fit in the back of a Suburban-Explorer type SUV or a pickup.
We need to come up with some highly portable way of
supporting the TH-3 up 30-40 feet that could meet this criteria if possible.
I would appreciate hearing from the tower guru's about ideas on how to
handle this situation.
As a possible alternative, we have considered some type of trailer mounted
tower system that could
easily be hauled to a location and erected at the site by a couple of people
EASILY. Any ideas or
suggestions about this possibility would also be appreciated. Portability
and ease of quick erection
are the keys to either of these options.....
Thanks
