KY6R Antenna Plots (Featuring the SteppIR UrbanBeam)

Along with my Fluke DVM, my Rig Experts AA-30 has seen so much use and helped me with antennas and feed and phasing lines that it rates as my top tool in the ham toolbox. One of the best things you can do – after you tune your antennas at their feed point – is to run the analyzer at your feedline(s) in the…

80M Base Switching Circuit

The circuit will be ready with just a few solder lugs and wire and mounting that heavy coil to the board. Then the board fits perfectly in the Bud Box: And this gets screwed into the redwood support of the vertical.

After reading Tom, W8JI’s page on Linear Loading vs. Coil loading: https://www.w8ji.com/loading_inductors.htm He says this – “Linear Loading is really nothing other than a poor form-factor inductor. The radiation from the linear loading does NOT change the radiation resistance of the antenna except as the effective position of the load might change from the direction of fold. In all cases, a proper form-factor inductor…
