After a few more summits, I’ve decided my SOTA getup needs serious work. The amateur radio community largely acts on instinct and legend, so I’d figure I actually do the math in creating an ultimate SOTA antenna.

Part 3 will cover anything and everything towards the wire antenna elements. Weight tradeoffs, guy lines, lengths, impedances, and more.

Introduction (from previous)

This introduction is visibile on my previous posts. Essentially, antennas perform best wtih current at the physically highest radiating portion. Thus a dipole or inverted vee would be the best choice for a lightweight, ultra-efficient SOTA antenna.

So, without further ado, everything you’ve wanted to learn about wire.
