OM,
It will likely not work as well as a dipole. Nevertheless, it will be a
fun project and
won't cost a lot. I'd use aluminum EMT in 1" with the bottom sitting on
a Coke
bottle and a few guys........low cost.
Or, you could get some aluminum tubing from a deceased CB antenna (the
radiator
on a 5/8 wave Super Thunder Talker Lightning Pro-XL Deluxe Radio Rambo
Commando Force Field Projector) is just about right and it has a dandy
attachment
at the base for a mast pounded in the ground.
Or, some tubing from Texas Towers and mount it on a wooden post with
ceramic
stand-off insulators.....see the ARRL Handbook.
Hang a loading/matching coil on the bottom and it will work (albeit
poorly) on 40
and 30 as well. For 20m, 15 radials, each 1/4 wave long should do you
well.
Enjoy!
