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
