Have your J-Pole and ground it too

1.06 GHz Test J-Pole Antenna

Tame the predictable mast currents found in any j-pole antenna grounding conductive mast using a simple stub. Shown is empirical evidence why this is a problem and a very simple solution all future grounded j-pole antennas should incorporate.

Coax Velocity Factor in Baluns, Does it Matter?  Part 2

Test results of the Coaxial Cable Balun and the Folded Balun (aka Pawsey Stub) reveal coax Velocity Factor applies to the former, but not the latter, unlike what many web sites would have you believe. Part 2 of 2.
