Title: Simple Dual Band 20m/40m Vertical
Post by: cybersean3000 on May 23, 2020, 09:06:47 PM
Has anyone ever build one of these?  The details of the coil and the 40m element seem to be missing from the video.  Is it really this simple?

Hello, I bet you could make a half-wave one by doubling the wire lengths... Like my
PAR 10/20/40... Using a 49:1 or 64:1 transformer of course..
