The PKW FDX 40
Windom is an off center fed multiband antenna. The feed point is located at about 1/3 of one end. At this point, the impedance is about 300 ohms for all bands. By using a 1:6 balun, the Windom can be fed with 50 ohm coaxial cable. PKW windom antennas are rated at 1 kW PEP.
All PKW wire antennas are made of twisted phosphor-bronze antennelitze with a UV-resistant coating and have black plastic UV-resistant insulators at both ends.
