Mapping the Radiation Pattern of a Fixed Long Wire Antenna

The simple 20 meter pull-up vertical antenna I described last time has been working well.  I've been putting my efforts into working DX stations and have found that the vertical often does almost as well as the Off Center Fed Dipole (OCFD) despite its generally lower gain.  Part of the reason is that there are...

The Off-Center-Fed Dipole Antenna – Design

There are a few ways to build multi-band HF antennas.  These include multiple resonant dipole arrays, trapped dipoles, resonant loops and the off-center fed dipole, OCFD.  I'm going to look at the OCFD because it is relatively simple to construct, yet gets quite decent performance.  I also am fortunate to have some nice tall trees...
