Mike:

The 160 meter sloper is about 40 feet off the ground at the feed point, and
the radiating element of the sloper is about 10 feet off the ground at the
far end.

I will check out the coax coil and adjust it accordingly.

Thanks so much for all your help.

I know the antenna is far from perfect, but hopefully, it will get me on 160
meters in one form or another until I can get something better up here next
Spring.

My problem overall is that I just don't have the property here for what I'd
really like.
