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, Towers, repeaters, routers, and access points for reliable RF signal transfer,5G, LTE, Wi-Fi, and satellite communication 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 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.
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 is 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.
