Diamond w8010 banden 80-40-20-15 en 10 meter
The antenna described here is known under different names. It is a combination of two dipoles that are shortened with coils and thus the bands 80-40-20-15 and 10
Carolina Windom antenna
It is an off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m
Multi-band antenna for the 80, 40, 20, 17, 12, 10 and 6 meter
Project for a multi-band antenna for the 80, 40, 20, 17, 12, 10 and 6 meter bands, including a 1:4 impedance transformer and a current balun handling 800 Watt with common mode attenuation up to 40 dB!
W3HH Multibands with Balun for 10/80mt
The antenna consists of a folded dipole originally fed by a two-wire 600 ohm impedance line
