Make sure you guy the poles, if you want them to last. The necks crack on them if there is a lack of support.Originally Posted by KJ6BSO

How high up there will your fingers be if they are on the antenna getting RF burns when the feds come to confiscate your Moxon?
Yeah, I've had a few break that way. It's guyed adequately for the 24-hour duration of FD. I'd add more if it was going to stay up for a extended period through bad weather but the stress on the poles is mostly in compression so it should be fine.

Are you going to have an erection party?

A bunch of olde phartes, gathered together in a nursing home room, wearing party hats, cake, one guy in the bed trying to sprout a tent pole and the other guys all cheering him on.
And in walks Nurse Melissa in her birthday attire.
The old guy in bed says
The pole is up
the tent is spread
take off your cups
and get in bed
To which she replies
Take down the tent
put the pole away

That's a bad monkey. It needs spanked.
Segueing back into the antenna component of this thread:
I got hold of a few bags of the military mast - both fiberglass and aluminum - over the years. 8 4' sections of the aluminum stuff makes a nice 40M vertical. A Moxon or some type of loaded Yagi (such as the design in the 7th edition ARRL Antenna Compendium) allows for working another band simultaneously and makes a nice capacitance hat.
A friend at work sold me enough surplus 40" car antennas that I can build and deploy 3-el loaded Yagis on 10, 15 and 20. There may be enough left over for a 4-5 el 6M Yagi too.
These can be built light enough that the metal mast has no trouble supporting them - and they can be turned via a rope at the end of the boom.

I have a "mixed bag" of aluminum and fiberglass military surplus poles just like that. With four guy rings and a "folding petals" heavy cast metal base. Got the whole thing from a guy that puts them together and sells 'em in CO Springs. Tops out at 58 feet. Just the thing for camping.
Most of the time I've deployed it to heights of 30-40' or so. A home-brew 6 meter Moxon was used at first, but now I pick one band from 20-6 and deploy the YP-1 Superantenna. Which I've had really good luck with, especially on 10 and 12 meters.

I have 12 of these camo poles 4 feet each and fiberglass green, setting them up each neck gets a stainless steel waterhose clamp around it protecting it from splitting, works fine, had it up before my inverted L as helically wound antenna for 160 se piccies at qrz on my page.
That was 15 meters high, guy wires at 13 and 9 meters high kept it up fine in some 60 knot winds...

This guy runs this add pretty much every week. 12 poles for $25. If it is a good price, he might ship. FWIW
