Overview
An RF surge arrestor (also called a lightning arrestor or surge protector) is a protective device used in RF systems to safeguard sensitive equipment from voltage surges caused by lightning strikes, electrostatic discharge (ESD), or power line disturbances. It is installed inline with coaxial transmission lines and diverts excessive transient energy to ground while allowing normal RF signals to pass with minimal loss.
Features
Protection: Defends radios, antennas, base stations, and test equipment from lightning-induced surges and transient overvoltages.
Frequency Range: Supports a wide bandwidth, typically DC to 6 GHz or higher depending on design and connector type.
Low Insertion Loss: Ensures minimal impact on signal transmission and VSWR performance.
Types: Gas discharge tube (GDT), quarter-wave stub, and hybrid designs are commonly used.
Power Handling: Capable of withstanding high RF power levels, making them suitable for base stations and broadcast systems.
Mounting & Connectors: Available in standard RF interfaces (N-type, 7/16 DIN, SMA, etc.) with options for bulkhead or inline installation.s.
Applications
Wireless base stations (LTE, 5G, Wi-Fi)
Satellite communication systems
Public safety radio networks
Microwave links and broadcast systems
RF/microwave test benches and calibration equipment
TV and radio transmission systems

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.

What is impedance, and why is 50 Ω or 75 Ω important?
Impedance matching prevents signal reflection and power loss. 50 Ω: Standard for RF communication, test equipment, aerospace, defense. 75 Ω: Standard for broadcast, video, and cable TV applications.
What materials are RF connectors made of?
Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and durability.
Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
