Shakespeare makes exactly what you want, but you can't afford it. It is
self supporting up to 15 knot wind, the nylon guys are necessary above that.
Shakespeare calls it a "Style 120-60", Military nomenclature is AT1011/U.

For Field Day we homebrewed a 32 foot vertical out of five swimming pool
poles. Secured to a six foot tripod with spikes in each tripod leg.

The radiator was a 32 foot length of zip cord.

Four radials (zip cord) were used at about the 10 foot level drooping

down.

SWR was 1:1.5 to one across the 40 M band

Used it on 15M as well with SWR less than 2.5 to one.

Antenna worked well across country on both bands. West coast to east

coast.

Next year I would like to refine it by replacing the swimming pool poles
with aluminum tubing (6 foot sections) where each section fits into the
previous one. Figure I will need 6 sections to allow for 4 inches inserts.
Then hose clamp them. May have to double up and use double wall tubing.

Trying to figure what diameter to start with at the bottom. Greatly prefer
NOT to use guy wires.

Another problem is insulating the 32 foot radiator from the tripod. Maybe

a
5 foot section of plastic pipe PVC ???

Maybe I am better off to use the swimming poles as they didn't fall down

for
24 hours (;-)

Ideas appreciated
