Antenna Windom
Windom did some experiments and found that if the dipole feeding point was moved, the amplitude of the currents for the different bands was such as to have the possibility of resonance on the even harmonics

Vertical Dipole
All radiators are 1/4 wavelength radials for individual bands are 5%
Wire antennas for the low bands
I have experimented with a variety of wire antennas. Any configurations have to fit in my 100ft long by 40ft wide garden
1/4 Slopers 40/15M Band
The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 MHz and the top fed sloper was the most convenient installation having the least impact
15-40-80mt Dipole
I have this balun installed on all my coax feeders
