Electrically Shortened Center-Fed Dipole - K7MEM

SpletI have used the "Shorty" on bands from 10 through 160 - It was impossible to tune on 160 as it came in the packaging, but a simple modification was all it took. Ditching the ladder line completely, and using a 9:1 balun as the dipole center, feeding with RG213, not only does the 40m issue go away, but it "flattens" the VSWR curve some.

20m 1/2-size dipole - Nonstop Systems

SpletThe performance is pretty much dipole-like on 40m and 20m. The higher bands were closed at the time. Extensive tests with WSPR on 80m showed it was about 8.5-12dB (perhaps 2 S points) down on a W5GI dipole at the same height. While this is not a big performer on 80m it will get you on a band that you might otherwise not have access to.
