Coaxial cable Rangeful SMA Male to SMA Female HF400 50 Ω flexible 7 m

Rangeful HF400 coaxial cable with SMA male to SMA female connectors, 50 Ω impedance and 7 m length is designed for reliable RF signal transfer in antenna and test setups. The cable uses a flexible HF400 construction that balances bendability and shielding for indoor routings and protected outdoor installations. SMA male to SMA female termination provides a threaded, compact connection suitable for many transceivers, antennas and laboratory instruments that require a 50 ohm interface.

Advantages

The 7 m HF400 cable delivers consistent 50 Ω characteristic impedance for minimal reflection and stable signal transfer across common RF frequency ranges. Its flexible dielectric and braided shielding reduce microphonics and allow routing in constrained spaces. Threaded SMA connectors ensure secure mechanical engagement and repeated mating cycles without significant degradation. The cable construction is intended to provide a practical balance between flexibility and loss, making it suitable for frequent rearrangement and testing tasks.

Suitable for

• Connecting antennas to transceivers and routers with SMA interfaces
• Radio communications setups and field testing where a 50 Ω link is required
• Laboratory and bench RF testing between equipment with SMA connectors
• Indoor or protected outdoor cable routing in installations that need flexibility

Key specifications

• Impedance: 50 Ω
• Connector pair: SMA male to SMA female (threaded)
• Cable type: HF400 flexible coaxial
• Length: 7 m
• Application: RF signal transmission for antennas, transceivers and test equipment

How to use

Before connecting, inspect SMA connectors for dirt or damage and ensure both mating surfaces are clean. Thread the SMA male connector onto the female receptacle by hand until snug, then use a torque wrench if precise torque is required by your equipment specifications. Route the cable to avoid sharp bends and tight radii that exceed the cable's flexibility limits; support long runs to prevent strain on the connectors. For temporary test setups, coil excess length without kinking and keep the cable away from strong RF noise sources or high-power transmitters to avoid unwanted coupling or overload.

Usage recommendations

Use the cable for indoor and protected outdoor connections; avoid prolonged exposure to direct sunlight or unprotected outdoor environments. When used in measurement setups, verify connector torque and perform a basic continuity or SWR check to confirm expected 50 Ω performance. Store coiled without sharp bends and clean connector interfaces periodically to maintain consistent RF performance.
