An antenna whip construction having a radiating or radiation receiving antenna element, and an isolation transformer electrically connected between the antenna element and the support fitting of the whip, and all of which is bound into a structural self supporting whip. The isolation transformer has a pair of input terminals for connection to a transmission line, and the isolation transformer allows feed through from one of the input terminals to the antenna element but effectively isolates the antenna element from the other of the input terminals.
