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, vehicle radar (24 GHz, 77 GHz for ADAS),cable TV distribution and headend 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.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.

Other: Aluminum, titanium alloy
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.
