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, TV and radio transmission systems,RF/microwave test benches and calibration equipment 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.

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.
What is the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
How do environmental conditions affect RF connectors?
Temperature extremes can cause expansion/shrinkage and change performance. Humidity and salt spray may cause corrosion (use stainless steel or weatherproof designs). Vibration may loosen bayonet types - use threaded connectors in harsh environments.
