Radiocommunication

Radiocommunication systems which are connected to an antenna are especially exposed to lightning strikes. The maximum risk is a direct strike on the antenna pole. Equipment such as GSM/UMTS or TETRA base stations must be protected from this risk in order to ensure service continuity. CITEL offers a complete range of surge protection technologies for all RF line applications.

  • Gas tube technology

    CITEL offers a range of coaxial surge protectors using gas discharge tube technology. The main advantage of this technology is its very wide bandwidth handling capability: from DC to several GHz

  • Quarter wave technology

    An alternative to the gas tube method of protection is the short circuit protector. This short-circuit is tuned to one quarter of the wavelength giving its name to "quarter wave protection".
