Overview
The F connector is a coaxial RF connector widely used for cable television, satellite television, and broadband internet applications. It features a threaded coupling mechanism that ensures a secure and reliable connection, minimizing signal loss and interference. Typically available in 75 ohm impedance, F connectors support frequencies up to several GHz, making them ideal for high-frequency video and data transmission,missile guidance, drones, and satellite payload systems and electronic warfare, military radios, and secure communication links . They are easy to install and compatible with standard RG-6 and RG-59 coaxial cables. F connectors come in male and female versions and are commonly used in residential, commercial, and broadcast systems for consistent and durable signal connections.
Features
The cylindrical coaxial contact delivers excellent RF performance along with smooth insertion and withdrawal.
Available in multiple PCB mount styles-including surface mount, edge mount, straight, and right-angle meeting diverse application requirements.;
Supports conductor sizes from 0.022 to 0.042 inches (0.559 to 1.067mm).
A single connector design accommodates a broad range of cable sizes, helping reduce part numbers and simplify inventory management.

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.

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.
