What size loop and how many turns should I use to create a RF choke with my
coax, right before the antenna?

8 to 10 turns on an 8 inch form, remove the form, with RG-8X or similar
"mini" coax. 6-8 turns with RG-8 or 213.

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.

(We still have quite a bit on the ground, it hasn't gone above freezing

Same here this snow will be with us for a

while, we got 3" +/- overnight


Perhaps Punxsutawney Phil won't see his shadow this year. You can then
exit the cave and enjoy something other than artificial light. It may
even put an end to your winter depression.
On another note, a friend of mine sold all his stuff this weekend after
selling his home and purchasing a condo. He gave me a KLV amp that needs
a new cord. Do you still need some help to get heard down here?
According to Mason, you sure do.
