This F-connector (F-type connector) is a coaxial RF connector used in 50 Ω coaxial networks for television, satellite, and cable internet applications. The connector is used in terrestrial television, cable television (DVB-C), satellite television (DVB-S), and cable modems (DOCSIS). The screw connection creates a mechanically stable and electrically reliable connection with low contact resistance. The F-connector is typically mounted on coaxial cables such as RG-6/U and RG-59/U. Specifications & features • Connection F-connector (male) • Screw / twist-on type • Quantity per piece • Housing zinc • Contact material nickel • Marking 3 rings • Impedance 50 Ω Installation For installation, the coaxial cable is first stripped, with the outer jacket and shielding carefully folded back. The dielectric insulation is shortened so that the central conductor is exposed and can function as a signal pin. The F-connector is then screwed onto the cable with a twisting motion without special tools until it is firmly secured. Correct installation ensures a good ground connection via the braid shield and stable signal transmission. This version is suitable for quick installation but offers less strain relief than compression or crimp connectors. Technical explanation The F-type connector is designed for high-frequency signals and maintains a constant impedance of 50 Ω, which limits signal reflections. With this type of connector, the central conductor of the coaxial cable acts as the signal pin, minimizing additional contact transitions. Ask a product question
