Almost identical to the 6-band version (Item No. 05005), there were
only the side lengths halved!
In Europe, a 1:6 balun is used for Windom (OCF) antennas usually. We use however,
a 1:4 current balun according to Guanella. In our view, this has the following
advantages:
- better adaptation on 80m
- high power capacity
- broadband matching
- good supression of currents on the outer coax shield
I have been working over 10 years on Windom antennas with this
1:4 current balun and I have performed many experiments. Both I
and my customers are always surprised about the good results of
this simple wire multiband antenna.
When operating at 100 watts an additional choke balun is not necessary.
But with higher transmission power, however, we recommend the use
of additional choke balun at the feeding point.
