QRO No Tuner Multiband Dipole
One of the last upgrades to the dipole before experimenting with high-power tuning was to change the 300 ohm window line to 600 ohm ladder line. The higher-Z open-wire lines experience less loss overall, which means that they can operate at higher SWR than the lower-Z lines for a given loss value

Antenna multiband 10,20,40mt
Bi-directional radiation perpendicular to the strands of the doublet Impedance from 50 to 75 ohms depending on the angle of the reverse V
Antenna Half Sloper Multiband 1.8, 3.5, 7, 14, 21, 28 MHz
I made about 25,000 QSOs on it mainly in international contests - in 1.8, 3.5, 7, 14, 21, 28 MHz bands. The antenna also works effectively in WARC bands
