Small, cheap, efficient vertical antenna for 40m.

  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.

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.

Those of us who live or have lived on a small urban lot know how difficult it is to design and build an effective HF antenna.  Space and nosey neighbors become major obstacles in your choice of antennas.  In this video uploaded by TWiT Netcast Network, George Thomas (W5JDX) talks with Vito Dipinto (VA3VMD) about his small, yet effective dipole antenna. Despite the limitations of Vito's antenna, he manages to make many contacts from his small urban property.  Vito's simple dipole antenna may offer some hope for radio amateurs facing severe space problems.  You can view the full episode at https://twit.tv/hn/316.
