Building an HF Vertical 1/4 wavelength monopole.

by kc4mcq | Posted on


Thanks to the "AmRad Podcast" for this exceptionally well-done tutorial on how to build a vertical 1/4 wavelength monopole antenna for the 20 meter Amateur Radio Band.

The video takes us through the design, construction, testing and use of this basic HF antenna.

Here are some comments from the "AmRad Podcast.":

Today I'm building an HF monopole for 20 meters. I go through a basic formula, for fun we model the antenna in MMANA-GAL, then I show you how I put it together and tune the elements. Stick around until the fireside chat at the end, and I talk a little bit about ground-mounted vs. above-ground monopoles.. and proximity to trees. This should be a lively debate in the comments section ;) Follow more stuff here: @tcurrentsource www.thecurrentsource.com
