Electromagnetic waves in this frequency range, called radio … WebIt was by Windom's name that the antenna became known. The Windom antenna is an off-center fed dipole with an unbalanced coax feedline. In 1937, the Windom was first described as a compromise multiband antenna. The antenna can be employed on 80, 40, 20 and 10m with considerable, though acceptable levels of VSWR.
