Coaxial Connector ALLNET ANT-ADP-FM-RSMAM

The ALLNET ANT-ADP-FM-RSMAM is a coaxial adapter that connects an F-type connector to a reverse SMA (R-SMA) jack. Designed for RF signal transmission, this compact adapter provides a stable mechanical interface between devices with F and R-SMA terminations. Its metal housing and precision contacts help maintain signal integrity in home and professional telecom installations where adaptation between different coax connector standards is required.

Advantages

The adapter offers a compact footprint that occupies minimal space in cable runs and patch panels while providing a reliable threaded connection on the F side and a secure reverse-SMA coupling on the other. Durable construction and plated contacts reduce corrosion and ensure consistent electrical contact over repeated connections. The straightforward mechanical design minimizes insertion loss and preserves impedance matching when used within its intended frequency range.

Suitable for

• Connecting household or satellite coaxial cables with F connectors to devices using R-SMA ports
• Adapting routers, modems, and wireless equipment to external antennas with F-type feedlines
• Temporary testing and measurement setups where connector conversion is needed
• Telecommunications and networking installations requiring compact adapter solutions

Key specifications

• Connector A: F-type female (threaded)
• Connector B: R-SMA male (reverse polarity SMA)
• Material: metal housing with plated contacts
• Impedance: suitable for standard 50–75 Ω coax applications depending on cabling
• Form factor: inline adapter, compact and lightweight

How to use

Attach the F-type side by screwing it securely onto the male F connector of the coaxial cable or outlet until it is hand-tight; avoid overtightening. Align the R-SMA male with the R-SMA female port and push until the coupling threads engage, then rotate as required to secure the connection. Inspect the connection visually to ensure the center contacts are aligned and clean. Use the adapter only with compatible cable types and connectors to avoid impedance mismatch or damage.

Usage recommendations

For best performance, use the adapter in installations where cable and device impedances match and keep cable runs as short as practical to limit signal loss. Avoid exposure to prolonged moisture or corrosive environments; if installed outdoors, use weatherproofing measures at the connection point. Regularly check connections for looseness or corrosion and replace the adapter if any physical damage or significant signal degradation is observed.
