Small, cheap, efficient vertical antenna for 40m
Erecting a full-sized 40 meter vertical antenna can present a challenge if you live on a small urban lot or are subject to HOA or other deed restrictions. In this well-paced, informative video from Colin (MM0OPX), we see how "linear loading" on a short mast can deliver almost the same performance as a full-sized 1/4 wave vertical antenna. Like all 1/4 wave verticals, be sure you have a decent ground radial system to complement the vertical element of your antenna.

Here are a few comments from Colin (MM0OPX): Demonstration of a linear loaded 1/4 wave vertical amtenna that shows (at least) in modeling that it is as efficient as a full size 1/4 wave. What do you think? Let me know in the comments below. Transcript Follow along using the transcript. Show transcript MM0OPX Field Radi
