RF Surge Protector protects 75Ω antenna feeder systems from lightning-induced surges while maintaining stable RF transmission. Its N-type male-to-female connection supports secure inline installation across broadband communication networks. Low insertion loss helps preserve signal strength, while high discharge capacity diverts damaging transient current away from connected transmitters, receivers, and amplifiers. A replaceable gas discharge tube simplifies maintenance and extends service value, making the unit suitable for cellular base stations, broadcast antennas, distributed antenna systems, and outdoor wireless sites worldwide.
Features
1. 75Ω RF Signal Protection: Designed for 75Ω coaxial cable networks, protecting antenna feeder signals without changing the system’s characteristic impedance.2. N-Type Male-to-Female Connection: The N plug-to-socket structure provides a secure inline connection for antenna feeders, base station cabling, and outdoor RF equipment.
3. Wide 0–3 GHz Frequency Range: Supports RF transmission across frequencies up to 3 GHz, making it suitable for broadband communication and antenna applications.
4. Low Signal Insertion Loss: Insertion loss of no more than 0.2 dB helps preserve signal strength as RF energy passes through the protection device.
5. High Surge Discharge Capacity: Handles nominal discharge currents up to 10 kA and maximum discharge currents up to 20 kA under an 8/20 μs waveform.
6. Replaceable Gas Discharge Tube: The integrated gas discharge tube can be replaced after deterioration, reducing the need to replace the entire protector.
7. High-Power RF Compatibility: Supports RF systems with output power up to 500 W, making it suitable for demanding antenna feeder installations.
Advantages
1. Preserves Antenna Signal Quality: Low insertion loss and high return loss reduce unnecessary attenuation and reflection within 75Ω RF transmission paths.2. Protects Expensive Feeder Equipment: Surge energy is diverted before it reaches receivers, transmitters, amplifiers, or other connected RF devices.
3. Supports Long Outdoor Cable Runs: The inline N-type structure is well suited to antenna feeders that may collect induced surge energy over exposed cable routes.
4. Simplifies Field Maintenance: Service personnel can replace the gas discharge tube rather than removing and replacing the complete housing.
5. Reduces Communication Interruptions: Reliable surge control helps limit equipment failures that may interrupt antenna and cellular communication services.
6. Handles High-Power RF Operation: The 500 W power capability makes the protector suitable for transmitter and feeder systems beyond low-power signal equipment.
7. Supports Harsh Temperature Conditions: Operation from −40°C to +80°C allows installation in equipment rooms, cabinets, and exposed communication sites.
Applications
1. Cellular Base Station Feeders: Installed between outdoor antennas and base station equipment to protect 75Ω coaxial feeder lines.2. Broadcast Antenna Systems: Suitable for RF feeder circuits carrying television, radio, or broadband broadcast signals.
3. Distributed Antenna Systems: Protects coaxial connections used to distribute RF coverage throughout commercial and public buildings.
4. Rooftop Communication Equipment: Used on exposed antenna cables that face elevated lightning and induced-surge risks.
5. Wireless Communication Sites: Supports antenna feeders used in cellular, telemetry, and fixed wireless communication installations.
6. High-Power RF Transmission Lines: Suitable for RF systems requiring N-type connections and transmission power up to 500 W.
7. Outdoor Antenna Cabinets: Installed at cable entry points or equipment interfaces to prevent surge energy from entering protected cabinets.
