Communication electronic brings a series of gas discharge tube surge arrestors. This slim line surge arrestor is designed with high-pressure contacts, premium plating, and is compensated to offer the best possible imd performance. The functionality of surge arrestor can be readily evaluated by using ordinary rf field test equipment. If there is no degradation of the vswr or insertion loss of the arrestor, then the surge arrestor is reassuringly functioning as a transient lightning protection device. Using vector or scalar network analyzers as well as a variety of other readily available field test equipment can make vswr and insertion loss measurements. No other maintenance is required. As obvious as it may seem, surge arrestor should never be installed or tested when a storm is occurring or approaching. This gas tube surge arrestor is broadband rf devices that are capable of allowing a dc bias to pass along the center conductor, while shunting the lower frequencies associated with lightning induced transients to ground. This device is to be installed in series of a rf coaxial cable [between antenna and coaxial cable]. This gas tube surge arrestor contains a field-replaceable gas tube element. Under normal operating conditions, this gas tubes element functions as a simple capacitor with a shunt capacitance of less than 1 picofarad. In the presence of a lightning-type transient, the gas within the element ionizes and switches the gas tube to a low impedance state. In this low impedance state, the gas tube passes any lightning surge current present on the center conductor to ground. Gas tube elements can divert lightning surge currents reaching a peak of 10 ka to ground without causing any degradation to the element.
