Towers - Grounding

Proper grounding is an essential component of any wireless network deployment.   MapleNet's grounding methods closely follow the "Motorola R56 Standards & Guidelines for Communications Sites".  The following is an overview of MapleNet's basic grounding philosphy. 

Capture the lightning strike to a known and safe attachment point. This is usually an air terminal which is a copper rod with a very fine point that is extended on the tower above all antennas. This air terminal is bonded to the tower structure so that a direct lightning strike is encouraged to hit the air terminal and transfer the energy directly to the tower rather than through the antennas or cables.

The energy is safely conveyed to ground through the tower itself. All coaxial cables are grounded to the tower at 75 foot intervals to insure that the tower and the cables are on the same voltage potential at all times. This also insures that any lightning energy that may get into the antenna and cable system will be grounded out to the low impedance tower grounding system.
