Windom antenna Length 78m, Well renowned antenna 1000W for the harmonic bands 80, 40, 20, 17, 12 and 10m. Somewhat more bandwidth than a dipole, and good SWR on all bands. In space-restricted environments, the antenna can be installed at an angle or non-straight layout. Antenna wire of PVC-coated steel wire. Includes balun 1:6, max, power load 200 or 1000 Watt SSB/CW, connector PL. The balun is located at one-third of the antenna length. The Windom antennas for 160-10m and 80-10m can be extended to work on 30/15m by adding two simple wires. The length of the cables is 9,5m for the longer part and 4,8m for the shorter leg, incl. the loops for the end isolators. The new wires are connected to the balun in parallel to the existing cables and should be installed as far apart from the existing wires. Either sloped to the bottom like an inverted Vee or to the sides, forming a crossed dipole.
