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
