ESP RF Series Installation In a building, connect in series with the coaxial cable near where it enters or leaves the structure, or close to the equipment being protected. On a mast, connect in series with the coaxial cable near the antenna/dish being protected. Install in a radio communications room, an existing cabinet or a suitable enclosure. Combined Category D, C, B tested protector (to BS EN 61643) suitable DIRTY CLEAN for RF systems using coaxial cables at frequencies between DC and 2.7 GHz and where DC power is present. Suitable for RF systems with power up to 2.3 kW. For use at boundaries up to LPZ 0 to A From line To protect against flashover (typically the service entrance location) equipment Earth through to LPZ 3 to protect sensitive electronic equipment. ESP RF 111A21 with N female connectors installed in series Features and benefits Restricts let-through voltage below damage levels of interface circuitry Very low attenuation and near unity VSWR over a wide range of frequencies ensure the protectors do not impair system performance Wide bandwidth means a single product is suitable for a range of applications, including the transmission of DC power Easily mounted and earthed via fixtures on the base of the unit ESP RF 111121 on a coaxial cable running between an antenna and an RF receiver Available with N, 7/16 DIN and BNC connectors Additional mounting plates give increased flexibility Robust white bronze plated aluminium housing (silver plate option) Accessories ESP RF BK1 Application Straight mounting plates ESP RF BK2 Use on coaxial cables to protect RF transmitter and receiver systems, including 90 angled mounting plates electronics located at the antenna or dish. Typical examples include cell sites, military communications, satellite earth stations and pager systems. They can ESP RF BK3 be used in applications where DC power is required to pass to the equipment. Bulkhead through mounting plate (single) ESP RF BK4 Part numbering system Bulkhead through mounting plate Furse RF protectors have six digit part codes, prefixed with ESP RF. The selected (for 4 products) digits define the exact specification of the required protector, e.g. ESP RF AABCDE Connector type - ESP RF AAxxxx The first 2 digits refer to the connector type: ESP RF GDT-x 11 - N type female AA - 7/16 DIN type female 44 - BNC female Replacement gas discharge tubes Line impedance - ESP RF xxBxxx 3rd digit refers to the line impedance. Currently (Where x is the correct GDT part only one option: code digit for your system. See 1 - 50 transmission line. GDT selection). Gas Discharge Tube (GDT) selection - ESP RF xxxCxx Select the 4th digit from the table at the bottom of next page. Selection of the correct GDT is critical in the effectiveness of using these protectors. Technical note For the correct GDT, take the maximum RF power or voltage of the system and select a GDT with a voltage/power handling greater than the system. These protectors are based on a Important note: When using the peak RF voltage to select the GDT, if the system is continuous transmission line a multi-carrier system the (in phase) peak RF voltage can be calculated as the total with a GDT connected between of all the single carrier peak voltages on the transmission line. this line and screen/earth, and Protector rating - ESP RF xxxxDx 5th digit specifies the protector rating. are suited for applications 1 - Higher specification 2 - Standard specification where DC is required to pass to the equipment.
