I want to build a home made omni for use on tower.

I want to feed it with coax and have lot of wire, copper pipe, tubing, basic
parts.

I have a pretty good tuner and will use the tuner to tune. Can anyone make a
recommendation as to how to make a not so complicated omni directional
antenna that practical?

I am thinking something about 6 to 10 foot in height only, I can make gnd
planes, but something I can tune to get most bands and simply omni function.
I want to get all bands and I run barefoot and just want to get on the air
with simplest, least complicated, easiest to build omni. I don't need a
electronics lesson in engineering design, just a website or two explaining
the simple build of the magical omni fed with coax that is the best I can
get for my situation.

Thanks
