Conventional fiberglass communications antennas intended primarily for mobile use such as in the Citizen’s Band radio service are either fixed-tuned by the manufacturer or supplied with one of a variety of mechanisms for tuning. These tuning mechanisms typically vary the length of the antenna or vary the value of an inductance incorporated into the structure of the antenna. Another means employs a tunable network in the signal line adjacent the base of the antenna.

Applications:

A so-called fiberglass antenna consists of a wire helically wound around a flexible fiberglass rod to provide an electrically long, physically short, and durable antenna. Such a construction is especially suited to low cost mobile antennas which are subject to extreme conditions of use.

Fiberglass antennas is designed specifically for the user requiring an antenna that will take the rigorous vibrations from a truck, handle rugged use, the extreme changes in cold weather, and still perform well.
