Acoplamento F-Type Televes 4173 fêmea-fêmea – latão niquelado, 75 Ohm, DC-3 GHz

For coaxial connections that demand a secure, low-loss link, the Televes 4173 F-Type barrel adapter stands out with its solid nickel-plated brass construction and full metal shielding. Unlike flimsy plastic couplers, this female-to-female adapter maintains a stable 75-ohm impedance across a broad DC to 3000 MHz range, making it a dependable choice for satellite, cable TV, and antenna systems. Its corrosion-resistant body and precision threading ensure repeated mating without signal degradation, even in outdoor or high-humidity installations.

Highlights

• Female-to-female F-Type coupler for joining two male coaxial cables.
• Nickel-plated brass body for durability and corrosion resistance.
• 75-ohm impedance with full metal shielding to prevent interference.
• Wide frequency range: DC to 3000 MHz (3 GHz) – ideal for satellite and cable.
• Low insertion loss (< 0.5 dB) and high return loss (> 20 dB) for clean signal transfer.
• Compatible with standard F-Type cables such as RG59, RG6, and RG11.

In daily use

Whether you are extending a satellite feed, repairing a broken connector, or building a structured cabling panel, this barrel adapter provides a quick and reliable inline connection. The straight, compact design fits easily in tight spaces, and the silver finish blends with most coaxial hardware. Because it is fully shielded, you can use it near power lines or other RF sources without worrying about signal leakage or ingress. Installers appreciate the consistent thread depth and smooth engagement, which speed up installations and reduce callbacks.
