Ham Radio Antennas

Painting aluminum successfully requires good preparation and an appropriate Zinc Chromate primer. I painted by 43 Foot Vertical antenna black.

A viewer asks about coax losses associated with using the “tuner required” 43 foot vertical antenna.

Resolving the mystique surrounding the 5/4 wave antenna comparing center and end fed approaches. One conclusion is the end fed 5/4 wave antenna shows little promise as a vertical antenna for terrestrial use.

Analysis to suggest you really can use a 2 meter J-Pole in the 70cm band.

Longer is not always better in the world of antennas. Such is the case of the 5/4 wave vertical antenna… a Super J-Pole Wannabe Antenna

Described is a unique Balun technique used for the navigation receiver horizontal dipole in Cessna aircraft.

This J-Pole, Monopole, Coaxial Dipole VHF EZNEC shootout addresses a comment made that no models exist for j-pole and coaxial dipole antenna simulation.

The EZNEC simulations of the 43 Foot Vertical and the BigIR Vertical HF antennas are summed up with some final thoughts on which to select if you can have only one.

The BigIR vs. the 43 foot vertical antenna at 80 meters.

Analysis of 43 foot vertical against the SteppIR BigIR vertical in the 20 meter band.
