Small, cheap, efficient vertical antenna for 40m.

Image
  Here's another fascinating antenna idea from Colin (MM0OPX). In this video, Colin shows how linear loading can reduce the size of 40 meter vertical antenna without compromising performance. This modification should appeal to radio amateurs who live on small urban lots or other land-restricted properties.

Here are some 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.

Cheap, compact 160m antenna ideas

Image
The 160-meter Amateur Radio Band is a fascinating slice of the RF spectrum.  Unfortunately, antennas for the "Top Band" tend to be large and a bit unwieldy. In this video from Callum (M0MCX), we learn about several reduced length 160-meter antennas that can used where space is at a premium. Included in this list are the inverted L, sloper, loaded vertical, compact dipole, and the Halo/Loop antennas.

Let's look at Inverted L, Sloper, Loaded Vertical a Compact Dipole and the Halo (loop). Let us consider the problem, walk the area and discuss how each would work.

Cheap, effective Moxon Beam Antenna for 10 , 11, 12 meters

Image
The antenna design popularized by the late Les Moxon (G6XN) is quite popular with radio amateurs on the higher HF bands (20 meters through 10 meters). In this video from Colin (MM0OPX), we get a thorough introduction to the theory behind the Moxon Antenna, as well as practical suggestions on building this outstanding HF antenna. Colin also supplies a parts list for this antenna. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Vu8uaZTvLiw. Here are a few comments from Colin (MM0OPX): Apologies for the video quality, my computer is creaking at the seams while rendering. This is an overview of my 10m Moxon project. This can easily be adapted for use on 12m or 11m. Here is the link to the bill of materials for this project - note I am still adding to this so please check back. https://docs.google.com/spreadsheets/...

If you can't erect a full-sized 1/4 wavelength vertical antenna for the 40 meter Amateur Radio Band, please try this linear loaded vertical from Colin (MM0OPX). Colin says this modified vertical can match the performance of a standard 1/4 wavelength vertical antenna. This antenna can find a place at your home station or in the field for portable operations.
