WHIP ANTENNA HIGH VOLTAGE PROTECTION DEVICE

摘要

A high voltage protection device for protecting personnel from injury or death as well as damage of radios and vehicles when a whip attenna comes in contact with ? high voltage power lines or the like and comprises a high voltage coaxial capacitance device which is coupled in series between the upper and lower section of a whip antenna. The capacitive reactance of the capacitance device is very high at power line frequencies and relatively low at RF frequencies. The capacitance element is comprised of two concentric cylindrical conductors formed in a fiberglass shell and separated from one another by a dielectric such as polytetra fluorethylene.
