Overview
The RF Surge Arrestor offers dependable protection against lightning and surge-induced damage in radio frequency transmission lines. Engineered to maintain signal integrity while safeguarding equipment, it is an essential component for RF networks operating in demanding outdoor and industrial conditions. Featuring broadband performance from DC to 18 GHz (model dependent), this surge arrestor ensures low VSWR (<1.2) and minimal insertion loss, preserving signal quality across various frequencies. The internal surge protection element -typically a gas discharge tube (GDT) - rapidly conducts transient surges to ground, preventing equipment damage without disrupting normal signal flow. Some models feature replaceable GDT cartridges for easy field maintenance.
The body is constructed from high-grade brass or stainless steel with a nickel or silver-plated finish to ensure corrosion resistance and excellent RF shielding. Options for 50 ohm and 75 ohm impedance, DC pass or block, and connector types such as N, SMA, BNC, TNC, and 7/16 DIN make it adaptable to most RF systems.
Applications include antenna feeders, base station transmitters, radar systems, wireless communication links, and microwave test equipment. Designed for long-term reliability, this surge protector meets the rigorous demands of modern RF infrastructure, ensuring stable performance, easy installation, and peace of mind in all weather conditions.

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 the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
