True indeed Charlie
It was such an observation by accident that clued me into the fact that
I needed a choke on a system with elevated radials the first time :)

To offer another view.....IMHO
Measure the impedance at the base of the antenna without the feedline
attached in any way. While watching your instrument (259B, VNA, etc),
touch the feedline *shield* to the radials at the base of the antenna.
If your instrument shows
no change in the impedance, the feedline shield isn't carrying "any"
current
and therefore doesn't need to be choked.

I have the same situation and no choke. IMHO the transmission line
is just
another random length radial. I don't have chokes on any of the
others either.

Hello, I have an inverted-L and the radials are laying on the
ground AND
the coax is on the ground too with radials right near the coax
run. Do I
need a choke to stop any feedline coupling/radiation, and if so,
where in
the feedline?
The antenna is in the woods so burying either the radials or coax
won't be
easy.
Many thanks, Kenny K2KW
