20m Projects - Beam Antennas

20 Meter Mini Yagi by KJ5VW
What I ended up with was a two-element mini-yagi that weighed less then 15 pounds, cost less than $30 dollars, could be disassembled into four-foot lengths, stored in the trunk of my car, and could be assembled in less than a half hour. Here's how I did it.

A full-size ( = ½λ) dipole antenna for the 20 mtr band spans about 10 meters (33 ft). Searching for a half-size half-size 2-element Yagi, I found the design by Gary Hanson (KJ5VW).

20m Covert Dual 3-Element Beams by G3ASG
By adopting to use a single reflector element which is common to both beams, the antenna can be made to fire in opposite directions.

It's a nice looking antenna, light, and works very well on 20m. I put it up temporarily for the BS7H operation, but it worked so much better than my delta loop that I wanted to put it up permanently.

In August 2004 I had a QSO with Joe Italiano, N9PH, and Joe told me that he was turning "Martha" my direction. Joe told me that she was a homebrew Hexbeam made with bamboo poles that he had bought at K-Mart.

With the success on the invisible attic wire beam, a lot of club members showed their interest on this trial and discussed possibility of similar application.
