OVR RF Series

5
Combined Category D, C, B tested protector (to BS EN 61643) suitable 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 1.9 kW.
For use at boundaries up to LPZ 0 to protect against flashover (typically the
service entrance location) through to LPZ 3 to protect sensitive electronic
equipment.

Features & benefits
• Very low let-through voltage (enhanced protection to • Very low attenuation and near unity VSWR over a wide
IEC/BS EN 62305) between all lines - Full Mode protection range of frequencies ensure the protectors do not impair

• Robust aluminium housing

Application Installation
Use on coaxial cables to protect RF transmitter and receiver In a building, connect in series with the coaxial cable near
systems, including electronics located at the antenna where it enters or leaves the structure, or close to the
or dish. Typical examples include cell sites, military equipment being protected. This should be as close as
communications, satellite earth stations, pager systems possible to the system’s earth star point (to enable a good
and emergency services communications systems. connection to earth). 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.

NOTE: These protectors are based on a continuous transmission line with a GDT connected between this line and screen/earth, and are suited for applications where DC
is required to pass to the equipment. OVR CCTV/B and OVR CCTV/T are suitable for use on coaxial (or twisted pair) CCTV lines.
For coaxial CATV lines, use the OVR CATV/F.
