UHF Type 50Ω N Male to N Female RF Lightning Arrester – UHF-JK(BLQ)

  • Ultra-Fast Response (<1ns): Proactive interception to secure sensitive electronics instantly.
  • Wide Frequency (DC-6GHz): Versatile coverage for models ranging from DC-2.5GHz up to 6GHz.
  • Low Insertion Loss & Superior VSWR: Ensures maximum signal integrity and transparent communication.
  • High Surge Capacity (20kA): Withstands heavy lightning strikes for an extended service life.
  • Bi-directional Protection: Effective surge suppression regardless of installation direction.
  • All-Weather Performance: Fully sealed design with a wide operating temperature range.
  • Flexible Compatibility: Multiple impedance and connector options for global applications.
  • Compact Inline Design: Space-saving form factor for seamless integration into existing runs.

The RF Coaxial Surge Protector (RF Lightning Arrester) is a critical protective component that ensures the stable operation of modern communication systems. Installed in series between the antenna and receiving equipment (such as base stations, satellite receivers), it is specifically designed to divert transient overvoltage and excessive current induced by lightning strikes or power fluctuations on the transmission line. Its core value lies in its ability to channel hazardous energy into the ground within nanoseconds, thereby effectively protecting expensive and sensitive downstream electronic equipment from damage. It minimizes system downtime and financial losses caused by lightning, making it an essential choice for building highly reliable outdoor communication networks.

We offer a comprehensive range of connector types and genders to fit your specific setup, including:

  • Interface Types: N-Type, TNC, SMA, BNC, UHF, and DIN 7/16.

  • Configurations: Male to Female, Male to Male, and Female to Female, including Bulkhead options for secure panel mounting.

  • Impedance: Available in both 50Ω and 75Ω versions to match your system’s requirements.

Application

  • Wi-Fi Networks
  • CCTV/Security Systems (for BNC 75Ω)
  • Ham Radio (for UHF)
  • Base Stations (for DIN/N-type)

Installation Guide

  1. Placement: Near cable entry or device input. (e.g., router or amplifier).

  2. Orientation: Bi-directional (either way)

  3. Grounding (Most Important): Connect a copper ground wire (at least 10-12 AWG) from from the screw (on the side of the arrester body) to a ground rod. 

  4. Weatherproofing: Wrap outdoor connectors with waterproof tape.

  5. Tightening: Ensure all coaxial connectors are tightened firmly to prevent signal loss (VSWR).

FAQ

A: Yes. These arresters are built with rugged, weather-resistant materials designed for outdoor environments. However, for long-term reliability and to prevent moisture ingress into the connectors, we strongly recommend wrapping the connection points with professional weatherproofing tape (such as butyl rubber and PVC electrical tape) after installation.

A: It depends on the model. Many of our CA-27RP and N-type series feature a replaceable Gas Discharge Tube (GDT). This allows you to easily restore protection by simply unscrewing the side bolt and replacing the internal tube if it has been triggered by a surge, saving you the cost of replacing the entire unit. (Note: Please check your specific model’s specifications or contact us to confirm.)
