[BVARC] HF Antenna Advice

[MIKE BRANNAN]

Years ago I used steel strapping around my chimney to hold a heavy dipole with large traps. Worked fine. Even went though several high wind events.  One removed a large portion of the roof.

I am working on setting up a HF radio for home. I have a ‘backordered’ IC-7300 which may show up one day. In the mean time, I am trying to plan for my HF antenna that will fit on my small lot.   I think I can run an 40-20-10-6 OCFD (*MFJ-2010) in a slope from a tree in my front yard, with the feed point hung off a mounted on chimney, and then on to a post above my fence in my backyard. I don’t have any trees in my backyard. Instead I have power lines across the back of the lot that I have to avoid.
