I'm not familar with the RS design as I don't look at their antennas
very much save TV antennas. Most of their purchases are not of RS design.
The copper tubing was just a good purchase at the time. You can use
aluminum tubing with no problem. A dipole is not quite omni as you know.
My design is a dipole. I believe I am familar with that design now that
I think about it. It reminds me of the antennas the elderly use with
their motorcoaches. Use mine and you'll get much better results.
To make it onmi just place it vertical. FM commercial uses circular
polarization anyhow.
