A shortened 40 meter rotary dipole
After using verticals for 40 meter and last year a delta loop this year I choose to make a rotatable dipole
40 meter top loaded vertical 7 MHz
My homebrew vertical antenna worked great for FD netting me 60 contacts in 23 U.S. states
40m Band, portable dipole
Scale 1:100 all dimensions in meters. Overall length 16.6 m, f = 7 MHz
40m Standard half-wave Dipole Antenna
My 40m coaxial dipole antenna worked surprisingly well, considering how many compromises it was dealing with
