Overview
The UHF connector is a threaded RF coaxial connector widely used in radio frequency applications up to approximately 300 MHz. It features a simple threaded coupling mechanism that provides a reliable mechanical connection, though it is not ideal for very high-frequency use due to higher signal reflection at GHz ranges. UHF connectors are commonly available in 50 ohm and 75 ohm versions and are frequently used in amateur radio, CB radio, and older RF communication systems. They are valued for their ease of installation, electronic warfare, military radios, and secure communication links,radar systems, avionics, and navigation equipment,robust construction, and suitability for low- to mid-frequency applications where durability and cost-effectiveness are key.
Features
Optional reducing adapters support a variety of popular coaxial cable sizes.
Solder termination types allow installation without special tools.
Crimp termination offers a cost-effective and efficient assembly method.
Large threaded coupling ensures a rugged and durable connection.
Designed for non-demanding applications, providing reliable performance at a low cost.

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.
