Theory and construction of a novel trapless center-loaded off-center-fed (cl-ocf) dipole or windom antenna for the 80, 40, 30, 20, 15 and 10m hf amateur radio bands

HF Windom antenna, cover 80, 40, 20 15, and 10 meters, antenna design

This multiband wire antenna it is an off centre fed dipole, with 10 feet of vertical radiator, needs no tuner on 40m, 20m and 10m and works fine on all bands above 40m with a tuner, and even below 40m on 60m, and 80m.

This article describes the characteristics of the Windom antenna and shows the results of several simulations made with MMANA-GAL, covering models optimized for the 20 m, 40 m and 80 m bands.
