I ran an EFHW at home until the tree in the backyard ate it during the last hurricane.

For bug out I can’t compliment it enough. I made a EFHW with dual mix 243 31s from Palomer engineers https://palomar-engineers.com/ferrite-products/ferrite-beads/FT240-3I-ID=1-4-AC-DC-Coax-Noise-Filter-RFI-Range-1-300-MHz-Mini-Pack-of-3-p491545766 I cut it resonate 40-10 and it handles everything great. I suggest buying nice capacitors! Choke your feed line if >50w as EFHWs can have some RF feedback. I made up diagrams if anyone needs it. There’s some great EEs out there that have way out done the design effort so great data in this world today. I’m just a gear head ME. Happy to help if anyone needs it. 73, KJ5HMX Sent from my iPhone On Aug 20, 2025, at 6:39 PM, Daniel Poirot via BVARC <[email protected]> wrote: K6ARK
