Coaxial cable Rangeful HF400 50 Ohm, SMA male to N male, flexible HF400, length 25 m

Rangeful HF400 50 Ohm coaxial cable with SMA male to N male connectors, 25 m length, is a flexible RF interconnect designed for antenna connections, test setups and signal routing where a durable 50 Ω link between SMA and N interfaces is required. The cable uses an HF400-type flexible construction to provide lower loss than thinner leads while remaining manageable in installations that require bends and movement. With standard 50 Ohm impedance and industry-compatible SMA and N male terminations, this cable connects equipment with mixed connector types without adapters.

Advantages

The cable offers a balance of flexibility and stable RF performance over its length, making it suitable for routed runs and temporary test connections. Using SMA male and N male connectors allows direct attachment to many antennas, transceivers, filters and laboratory instruments. The HF400 construction reduces insertion loss compared with light-duty jumpers while keeping the cable flexible enough for confined spaces. The 25 m length lets users bridge distances between indoor equipment and outdoor antennas or connect remote racks without intermediate splices.

Suitable for

• Amateur radio antenna feeds and station setups
• Base station and repeater connections
• Laboratory RF test benches and measurement rigs
• Temporary field installations and event wiring
• Equipment interconnects where SMA to N conversion is needed

Key specifications

• Characteristic impedance: 50 Ohm
• Connector type: SMA male to N male
• Cable type: flexible HF400 construction
• Length: 25 metres
• Intended use: RF signal transmission and antenna connections

How to use

Inspect connectors and cable for visible damage before installation. Attach the SMA male end to the SMA-female port of the device or adapter, ensuring the threaded connection is hand-tightened and then secured with an appropriate torque wrench if precise torque is required by the connected equipment. Connect the N male end to the N-female antenna or equipment connector, again hand-tightening and applying specified torque if necessary. Route the cable to avoid sharp bends, kinks or tight radii, and secure with cable ties or clamps at intervals to prevent strain on the connectors.

Usage recommendations

For reliable RF performance, avoid bending the cable tighter than its recommended minimum bend radius and keep the run clear of high-power mains or noisy equipment. Use proper torque values on SMA and N connectors to prevent damage and to maintain consistent electrical contact. When deploying outdoors, protect connectors from moisture with appropriate waterproofing or enclosures.
