You can buy mast sections on E BAY made of either aluminum or fibre glass
( which can interconnect) upon which you can stick on aluminum(sticky back)
tape. They come in about 50 " lengths and slide into each other. You can
also buy a tripod connection into which you can place fibre glass sections.
Diameter of mast is about 2" From memory a 50 foot pole was less than $50.
You could also add telescopic Roach (crappie) fishing poles which are 20'-0"
long which are also on E Bay at about $30 for two. There are lots of
inexpensive ways to make antennas for field day and hikers.
Have fun

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
