![]() 2 tinned copper wire and the circles are grounding rods. ![]() 2 tinned copper wire should also form a ring around the grounding rods, as illustrated in Figure 4.23. ![]() These connections should be exothermically welded to the tower legs.On tower structures, a grounding rod should be placed off of each leg with a No.By creating a common ground, you have created a path of least impedance for all of your equipment should lightning cause an electrical surge.The grounding rod should be at least 6 feet long and should be fully driven into the ground, leaving enough of the rod accessible to attach the ground wires to it.One way of creating a common ground is to drive a copper rod into the ground and connect your electrical and electronic equipment to this rod by using wires or straps (grounding wires).Grounding rods and wires are also used to create what is referred to as a common ground.This low-impedance path is installed to encourage the lightning to travel through it instead of through your expensive electronic equipment.A grounding system, which is made up of a grounding rod and wires, provides a low-impedance path to the ground.When lightning strikes an object, it is looking for the path of least resistance, or more specifically, the path of least impedance.Cable grounding kits can be installed near the antenna and at every 100 feet.įigure 4.22 Installation of lightning protection equipment Most installations place the lightning arrestor at the egress to the building.After a lightning arrestor has performed its job by protecting the equipment from an electrical surge, it will have to be replaced, or it may have a replaceable gas discharge tube (like a fuse).Figure 4.22 shows a properly grounded radio, cabling, and antenna.Therefore, the lightning arrestor is typically placed closer to the antenna, with all other communications devices (amplifiers, attenuators, etc.) installed between the lightning arrestor and the transceiver. ![]()
