Thanks. I am going to use LMR-400. I assume that is about the same thickness as
the RG-8.

Yes.. Roughly equivalent. What's the application? You building a dipole
or an inverted V?



Sticking a 6 foot Firestick in the attic, using eight 9' wires as a ground
plane. Then when the weather warms, I stick a Imax in a tree.

You shouldn't need a choke for that, but it won't hurt either. Keep the
plane of the coil perpendicular to the antenna (the firestik) in that
setup, and drape the wires for the ground plane over the top of it.. If
you can get a foot or two separating the coil/choke and the ground plane
wires.

That is going to be tough. I can definitely get it under, but not by a a foot.
When you mean perpendicular, you the outer edge of the coil directly under the
antenna, king of the antenna point up at 12 o'clock at the coil? At least, that
is the way I remember perpendicular, being a vertical touching the horizontal
forming a T.

No.. that would be parallel..

Make a circle with your forefinger and thumb. Stick your other
forefinger thru it.. That's how it should look, only not touching. If
you can't get it a foot up, get it as far up as you can, and drape the
ground plane wires over top of the coil. Not REALLY critical, but it
will help with matching.
