KNX (AM) - Antennas

Antennas

The station's antenna array includes a tall main antenna (195 electrical degrees; optimum and much better than average for a Class A station's main antenna), and a shorter emergency antenna (135 electrical degrees; much better than average for a Class A's emergency antenna but inadequate for a Class A station's main antenna), with only one antenna being active at a time. An experiment in the 1960s which utilized these antennae in a directional setup during the daytime, only, was abandoned and the emergency antenna was later relocated when much of the site was dedicated as a park. The residential area currently to the immediate south of the main antenna was formerly the site of the emergency antenna. The circa-1936 main antenna was replaced after it was destroyed by vandals on September 14, 1965. An unused 365 foot tower was brought in from KFAC-AM and used while a new 494 foot tower was constructed. These two towers exist today with the 365 foot tower serving as an emergency antenna. Non-directional Class A stations are expected, and are, with few exceptions, required to have emergency antennae.
