As many wireless units are damaged by earth potential surges due to incorrect grounding as direct surge voltage is very difficult to protect against direct lightning strikes but the probability of a direct strike at any one location is very small Unfortunately power line surges and electromagnetic energy in the air can induce high voltage surges from lightning activity several miles away 16 2 1 ANTENNA GROUNDING Electromagnetic energy in the air will be drained to ground via any and every earth path An earth path exists between the antenna and the WaveNet and to protect against damage this earth path current must be kept as small as possible This is achieved by providing better alternate earth paths Itis important to ground the antenna to the same ground point as the WaveNet Antennas are normally mounted to a metal bracket which should be grounded to the WaveNet earth connection Surge energy induced into the antenna will be drained first by the mount s ground connection second by the outside shield of the coax cable to the ground connection on the radio 94 RE SYSTEMS WaveNet Wireless Monitoring System User s Manual Document UM 1002 Revision Level A and third by the internal conductor of the coax cable via the radio electronics This third earth path causes damage unless the other two paths provide a better earth connection allowing surge energy to bypass the electronics When an antenna is located outside of a building and
