Description
The N-type surge protector is a heavy-duty safety component designed to shunt high-voltage transients to ground before they can reach and damage sensitive electronic equipment. This variant features an N-Type Male to N-Type Female (Plug to Jack) inline configuration, allowing it to be easily installed between an external antenna lead and the equipment port. Optimized for applications up to 3GHz, it provides a wideband solution for high-power signals, including 4G/LTE, GPS, and industrial Wi-Fi.
The device utilizes a Gas Discharge Tube (GDT) mechanism that triggers at a specified voltage threshold, redirecting the surge to a dedicated grounding terminal. Its robust construction ensures minimal insertion loss and excellent return loss, maintaining signal integrity while providing a sacrificial barrier against electrical surges. Manufactured with a ruggedized nickel-plated brass body and premium PTFE insulation, it is specifically built to withstand the harsh environmental conditions typical of outdoor tower and rooftop installations.
Key Technical Advantages
-
High-Power Capacity: The N-Type interface is designed to handle significantly higher power levels than smaller RF connectors, making this protector ideal for transmission systems.
-
High-Frequency Performance: Supports a wide frequency spectrum from DC to 3GHz, making it compatible with 4G/LTE, GPS timing systems, and 2.4GHz WLAN.
-
Rapid Response Time: The integrated gas discharge tube reacts nearly instantaneously to voltage spikes, providing superior protection against lightning-induced transients.
-
Inline “Pass-Through” Design: The M/F interface allows for simple integration into existing cable runs at the point of entry or directly at the equipment port.
-
Weatherproof Design: Features a precision-machined body and internal gaskets to ensure reliable electrical performance in high-humidity and outdoor environments.
