Many thanks for the responses to my query. Found a 22 foot fiberglass Flag
pole on E-bay. That plus 10 foot of aluminum mast should do the trick. And
guy ropes are in order as suggested.

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
