Protection of radiocommunication equipment. Radiocommunication systems, connected to antennae, are especially exposed to lightning phenomena, the maximum risk being a direct strike on the antenna pole. Equipment, as GSM/UMTS or TETRA base stations, must consider this risk in order to insure a relevant service continuity . . .

P8AX Series RF Coaxial Protectors

Model: P8AX Series - Origin: CITEL / France
The P8AX series is based on gas discharge tube (GDT) and designed for RF line surge protection. Available for different power and with coaxial connectors (N, BNC, TNC, UHF, SMA, 7/16, 7/8 cable), P8AX units could be provide in feedthrough mounting version and with vari- ous impedance (50 or 75 ohms).          .

PRC series «Quarter-Wave» Coaxial Protectors

Model: PRC Series - Origin: CITEL / France
The other way to protect antenna lines is relevant replacement of the gas tube by a proper short-circuit chosen according to the operating frequency band. This short-circuit is tuned to one quarter of the wavelength, giving its name to «quarter-wave protection». This tuned short-circuit between the conducting core and the external ground acts as a band-pass filter. . Detail
