Thanks for the response and the calculations Don. Lots of offline responses to my query. The antennas use 90 radials 40' to 150' with the average at 66' Your option B is the way I configured the L network and your numbers are very close to mine. The second variable cap was set aside to use the

I have revised my question to correct the length of the antenna in question Topbanders In the past, I've posted some questions related to making my 80 meter verticals (64' tall ground mounted) work on different bands. The pair is spaced at ¼ wl on 80m and then I switch in base loading to reso

Topbanders In the past, I've posted some questions related to making my 80 meter verticals (64' tall ground mounted) work on different bands. The pair is spaced at ¼ wl on 80m and then I switch in base loading to resonate the same pair on 160m which are then effectively spaced at 1/8 wl. Now
