And, neither do I. (well, 11m band--sometimes. Just for medicinal
purposes, mind you. evil grin)

I have pursued the "Ultimate 10M Antenna", and a yaga or quad is/are
great. However, I like a omni to listen for traffic on. And, when
there are high winds, I like to point those directional antennas into
the wind. (have stripped too many rotor gears and suffered too much
damage in past decades)

Like you point out, and I concur, the perfect Omni which throws no rf to
the sky is elusive ... strange too, we can do it with light.

I have gotten used to the "RF GODS" extracting their portion of my rf
field to their realms in the sky (sometimes they toss a bit back to
australia though, I like the women there )
