I can do with one for a vertical. Anybody else had the same idea !!!.

Dirty and ugly option has to be an unun maybe a 9:1 (dependent on planned / hoped bands) a coax feed and some ground mounted radials. Unless of course you want to cut it as a mono band vertical. Mount the pole in a wooden or other non metallic base.

In reality a CB vertical like a silver rod would be easier to adapt and mount. But the scaffold pole would look more like a flag pole so may attract less glances especially if it holds a flag.

I have one strapped to a wooden pergola, its got a cobweb on the top at the moment.
I also have a palstar tuner doing nothing. I was wondering if anybody had already built
a vertical using a standard 21 ft pole, and made it work. If so how did they do it.
Keep the ideas coming though, it must be possible.

hi there have a search on sgc 230 tuners they will tune any bit of metal you can find so longs you have a good ground system.

shunt feed the pole & lots of radials dependent on the operating freq required.
