Overview
The 4.3/10 connector is a compact, high-performance RF coaxial connector designed for use in modern telecom and mobile network applications. It features a snap-on coupling mechanism that provides reliable, quick, and vibration-resistant connections. The connector supports 50 ohm impedance and broadband performance, making it suitable for frequencies up to several GHz. Its smaller footprint compared to traditional 7/16 connectors allows for denser antenna and base station designs without compromising electrical performance. The 4.3/10 connector is widely used in LTE, 5G, railway communications and signaling systems,in-vehicle infotainment and connectivity systems and other wireless infrastructure, offering excellent durability, low passive intermodulation (PIM), and ease of installation.

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’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.
What is VSWR, and why does it matter?
VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
What are typical applications of RF connectors?
Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
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.
