Antenna manufacturers utilize shunt-fed dc grounded antennas as a means of impedance matching and providing some form of lightning protection to their customers. It has been proven that these antennas do work and should be used as a means of diverting a portion of the direct strike energy to the tower and its ground system. Unfortunately this protection is designed to help the antenna survive and not the equipment. A direct hit, or even a near hit, can “ring” an antenna whether it is grounded or not since it is a tuned (resonant) circuit.
