Sorry, I didn't realize we'd been through it before. If you'll tell me
the date, I'll look up the postings and review them.

There are two things which can cause current on the feedline. sniped

I don't remember if you were involved or not Roy. It's been about 10
years ago.
One I remember is Tom Raunch (hope I spelled that right).
We argued for weeks about the OSJ until I sent him one.
Some tried modeling it, some even claimed it would not work at all.
The OSJ has been around for a long time, I did not invent it, I just
build it better.
I guess all antennas have feed line radiation and/or common mode
currents to some degree.
I suppose with the right equipment you can measure anything.
But I think most would find a big difference between an OSJ & a CSJ
Just because two antennas look similar, don't mean they work the same.

Ok, that was fun, But I have wasted enough time, I got to get back to
building Antennas.
