Small, cheap, efficienct vertical antenna for 40m.

Image
  If you need a more compact sized antenna for the 40 meter Amateur Radio Band, please try this linerally-loaded 40 meter vertical antenna. According to Colin (MM0OPX), this antenna design is "small, cheap, and efficient."  This antenna can fit a moderately sized urban lot with plenty of room for a ground radial system.

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.

  If you need a compact, efficient vertical antenna for the 40 meter Amateur Radio Band, then this linear loaded 1/4 wave vertical antenna is for you!. In this video, Colin (MM0OPX) shows us how to design, build, test, and use this antenna design.

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.

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.

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.
