The following table summarizes the net effective loss for the three connection scenarios outlined above. In
general, for the 2.4 GHz operating frequency band, Scenario 1 will have an additional loss of 3.0 dB, Scenario
2 will have an additional loss of 4.9 dB and Scenario 3 will add a loss of 6.9 dB.
Surge suppressor (lightning arrestor)
The Nortel series gas-discharge surge suppressors (lightning arresters) provide high-level protection for
transmitters and receives at RF-communication sites. In the event of a local strike, the unit’s gas discharge tube
ionizes instantaneously to limit sudden voltage surges across the coaxial line. When connected to a satisfactory
ground, the unit can safely shunt up to 5000 Amps of impulse current away from sensitive station equipment.
