Coaxial cable Rangeful HF400-RPTNCM-SM-3 3 m SMA male to RP-TNC male UltraFlex HF400 series

Rangeful HF400-RPTNCM-SM-3 is a 3 m UltraFlex HF400 series coaxial cable with SMA male to RP-TNC male connectors designed for RF signal transmission. The cable combines a flexible HF400 construction with precision SMA and reverse-polarity TNC terminations to provide a short, bendable jumper suitable for test setups, communications equipment, antenna connections and laboratory use where reliable connector mating and ease of routing are required.

Advantages

The UltraFlex HF400 construction delivers improved bend radius and handling compared with standard RG-style jumpers, enabling neat routing in confined spaces. SMA male and RP-TNC male connectors ensure secure mechanical coupling and correct polarity for compatible devices. The 3 m length balances reach and signal integrity for short-run connections while minimizing excess cable bulk. The assembly is intended to provide consistent RF performance across typical VHF/UHF test and communications bands when used within its rated frequency range.

Suitable for

• Laboratory and bench RF interconnections for testing and measurement
• Connecting communications equipment, transceivers and modems to antennas or attenuators
• Windings and routing in racks or enclosures where flexibility is needed
• Temporary or semi-permanent jumper connections in field deployments

Key specifications

• Cable type: UltraFlex HF400 series coaxial
• Length: 3 meters
• Connector A: SMA male
• Connector B: RP-TNC male (reverse polarity TNC)
• Design: low-profile, highly flexible RF jumper
• Typical applications: RF test, communications and antenna interconnects

How to use

Ensure both mating connectors are clean and free of debris before connection. Align the SMA male and RP-TNC male connectors with their respective ports and engage by hand; avoid cross-threading. Tighten SMA connector finger-tight and RP-TNC connector until secure—do not overtighten with excessive torque. Route the cable following gentle bends and avoid sharp kinks; maintain a bend radius consistent with flexible HF400 constructions. For long-term installations, verify mechanical strain relief at connection points to prevent connector stress.

Usage recommendations

Use the cable within its intended frequency and environmental ranges; avoid exposure to corrosive chemicals and prolonged UV if used outdoors. If higher insertion loss or degraded performance is suspected, inspect connectors for damage and replace the cable to maintain measurement accuracy and reliable RF links.
