Ham Radio - Building a spiral loop antenna for 20 meters

NOTE: SM0VPO is not Richard. He’s Harry Lythall. My apologies to Harry. I've wanted to try out a spiral loop for awhile. I loosely followed Frank, N4SPP's notes on his page, which as of 2026 is gone.. So I found the page his was based on, with the loop project. Pretty easy to throw together, broader bandwidth than a traditional magnetic loop. https://sm0vpo.com/antennas/20m_ant_0...
