Coaxial cable Rangeful HF400-SM-PL-15 — SMA (male) to PL259 UHF, 50 Ω, full copper, 15 m

The Rangeful HF400-SM-PL-15 is a 15 m coaxial cable with an SMA male connector on one end and a PL259 UHF plug on the other. Designed with a 50 Ω impedance and full-copper conductors, this cable is intended for HF and VHF radio applications, antenna feeders, and direct connections between transceivers and external antennas or equipment. Its length and flexible construction make it suitable where extended reach and consistent RF performance are required.

Advantages

The cable features full-copper inner conductor and shield for reliable conductivity and reduced signal loss across the 15 m length. Its 50 Ω impedance matches standard amateur and commercial radio equipment, providing stable transmission characteristics. The SMA (male) to PL259 (UHF) interface allows direct connection between devices with these common RF ports, eliminating the need for multiple adapters. The construction balances flexibility and mechanical durability to support routing in stations and temporary field setups.

Suitable for

• Connecting transceivers with SMA outputs to equipment or antennas with PL259/UHF inputs
• HF and VHF antenna feeders where a 15 m cable length is required
• Amateur radio stations, commercial radio installations, and field operation setups
• Test and measurement scenarios requiring a flexible, low-loss RF cable

Key specifications

• Connector types: SMA male to PL259 (UHF) plug
• Impedance: 50 Ω
• Conductor material: full copper (inner conductor and shield)
• Length: 15 metres
• Cable category: coaxial cable suitable for HF and VHF frequency ranges

How to use

Inspect both connectors and device ports for cleanliness and secure threads before connection. Hand-tighten the SMA male onto the corresponding SMA jack without over-torquing to avoid damaging the connector. Align the PL259 plug with the UHF socket and screw it in until snug; avoid excessive force to preserve connector threads. Route the cable to minimize sharp bends and avoid kinks; maintain a bend radius consistent with flexible coaxial cable practice to reduce insertion loss. When connecting to external antennas or feedlines, ensure proper strain relief at the ends to prevent mechanical stress on the connectors.

Usage recommendations

For optimal signal integrity, keep cable runs as short as practical and avoid coiling excess cable tightly. Regularly check connectors for corrosion or looseness, especially in outdoor or humid environments. If used near high-power transmitters, verify that the cable and connectors are rated for the intended power levels and monitor for heating during operation.
