The bridge simulates having your [likely] ferrite loop antenna on a 750 foot tower, which at 1020 kHz is about 0.8 wavelengths. All the rest of the way to Forest hill [and anywhere else], your ferrite

Greetings, Please enjoy the photographs in Club Dropbox from Endura Race 2021, Darling Ridge post. AI6US and AI6JB ran HF during the weekend with a homebrewed 80m antenna at 100', launched into treeto

The attached graphs show, in meters, specific lengths to "avoid" when planning a longwire antenna. Matching will be virtually impossible if you happen to land on one of these lengths. Of course, heigh

I should probably mention also that the inverted V configuration for NVIS is very easy, but not ideal because it can pick up significantly more noise from (1) moderate distance lightning storms, and (
