F to SMA connector F to SMA RF adapter SMA coaxial converter F-SMA signal transition connector gold-plated F SMA RF coaxial plug antenna connector

Product Description

This full-series F-to-SMA RF coaxial adapter realizes bidirectional signal conversion between F-type (75Ω CATV standard) and SMA (50Ω wireless communication standard) interfaces, including four mainstream combinations shown in the picture: F male to SMA male, F male to SMA female, F female to SMA male, F female to SMA female.

The main body is forged from solid brass with matte nickel plating for corrosion resistance; central contact pin adopts thick hard gold plating to avoid oxidation and signal attenuation after long-term use. Partial models are equipped with knurled anti-slip outer nuts, allowing hand tightening without tools for quick disassembly of household antennas and TV equipment.

Working frequency covers DC~3GHz, fully compatible with digital cable TV, satellite receiving signals, 2.4G WiFi router external antennas, amateur radio short-distance signal transceivers. Built-in PTFE stable dielectric core ensures low VSWR signal transmission, avoids picture flicker and signal loss caused by interface mismatch. All raw materials comply with RoHS environmental protection standards, suitable for household consumer electronics and small wireless communication equipment assembly.

FAQ

Q1: What is the advantage of knurled nut version compared with ordinary smooth hex nut?

A: The surface dense diamond knurling increases friction, can be manually screwed tightly without matching open-end wrench, very suitable for ordinary household users to independently install and replace antennas; smooth hex nut needs wrench for precise locking, more used for fixed equipment professional engineering wiring.

Q2: Can this F-SMA adapter be used for outdoor wall-mounted satellite dish antennas?

A: The nickel-plated shell has certain anti-rust performance, but this adapter has no integrated waterproof sealing ring; if used outdoors for a long time, it is recommended to wrap the joint with waterproof heat shrink tube to avoid rainwater vapor entering and causing signal short circuit.

Q3: What is the maximum working frequency of this F-SMA adapter?

A: Nominal stable working frequency DC~3GHz, fully supports all digital cable TV, satellite TV and 2.4G WiFi signal transmission; it cannot be used for 5.8G WiFi, millimeter wave and other high-frequency signals above 3GHz.
