And even if you found a super laboratory scale
that actually could measure the mite departing, I would STILL
say the event does not matter. Your mileage may vary, of course.

Yes it varies a good deal...I'm not willing to throw away 3-4 S units
worth of low angle gain in the case of the ringo ranger.
It would take many mites to make up the difference.
Of course, the degree would vary to each persons
feedline. I was using about 50 ft.

Last but not least, if someone posts valid data showing that the
performance of an OSJ J-pole can be measurably, repeatably,
and significantly improved by a decoupling device, I'll be grateful
to him/her!

I've tested it, but I didn't collect data, other than in my head.
But there is no doubt that adding decoupling would make
the performance the same for any user. This will not be the
case without it. All decoupling will do is make sure you
get the gain you are supposed to. It's not going to help an
antenna that has little common mode problem to begin
with.

I suppose Al would have to have a poll....If the owners were
interested in the test...I don't really like J poles that much,
so I know I'm not going to waste my time repeating something
I did 20 years ago...

And if the decoupling device is practical and affordable,
I'll want to know where to buy one, or how to build one.

I've already described one simple version...I've tested it,
and I know it works. There are many ways you can do it..
