LHS Episode #319: HF Homebrew Antennas Deep Dive
Welcome to Episode 319 of Linux in the Ham Shack, the first episode of the new decade. In this episode, the hosts discuss what you might need in terms of money, knowledge, supplies and elbow grease to build a number of different effective HF antennas, both single- and multi-band. If you were wondering if you should put up a commercial mega-tenna or build something out of copper pipe and spare insulators, check out this episode. It is the first in several deep dive episodes concerning antennas and antenna theory. Hope you enjoy.
