<< Or, how do you get bandwidth on a dipole? >>

1. Use a 1:1 ferrite choke at the feed point (Aztec preferred) or a coax
2. Use 12 gage wire (14 minimum)
3. Make it horizontal and get it at least a half wavelength in the air.

I modeled 80 meter and 160 meter antennas for K5XI for endless hours. We wound
up with dipoles between the 260', the 220' and the 140' towers that were
killers. Of course, it's nice to be able to get an 80 meter antenna over 1/2
wavelength in the air.

At my QTH, my 80 meter dipole is under 2:1 from 3.520 to 3.800 since I started
using a choke at the feedpoint.
