Hi All.
I made Single Line Feeder Windom Last weekend.
Matching (tuner) Unit: FC40 Yaesu endfed tuner, Radio Yaesu FT897.
Antenna was working against ground system, tuner at 3 m height.
Antenna was inverted V position, highest point 11m from ground,
hanging from feeder connection. Angle abt 120 gedrees.
Wire ends more than 5 meters from ground.
Dimensios at start:
Longer wire 28m (91.8 ft), Short Wire 14 m (45.90 ft) ,
Feeder 8.2 m (26.90 ft)
First I got good match all HF bands 1.8 MHz to 29 MHz except 7 MHz.
After some calculations I shortened longer wire 75 cm and I got
perfect 7 MHz tune, But same time I lost 3.5 to 3.6 Mhz match.
After many canges I finally got this windom working at all HF bands:
Dimensions at the end:
Longer wire 27.35 m (89.7 ft) , Shorter wire 13.45 m (44.10 ft) ,
feeder 8,2 m (26.90 ft) .
It was not enough time for DX testing, but local (10 to 300 miles )
QSOs at 80 and 40 m Gave similar reports between horisontal full
size G5RV and this Windom.
I did good experiment, easy, cheap and fast made antenna giving OK results.
