Coaxial cable Rangeful PL259 to SO239 UHF, HF400 flexible 50 Ω, length 7 m

Rangeful HF400 coaxial cable with a PL259 (male) to SO239 (female) UHF connector pair is a flexible 50 Ω cable designed for HF and VHF radio applications. At 7 m length the cable provides a practical balance between reach and signal integrity for transceivers, base stations and portable setups. The HF400 construction delivers mechanical flexibility for indoor routing and temporary installations while maintaining consistent characteristic impedance for reliable RF performance.

Advantages

The cable combines standard UHF connectors (PL259 to SO239) with a flexible HF400 dielectric and braided shield to reduce handling stress and allow easier cable management in tight spaces. Its 50 Ω impedance matches common amateur and professional HF/VHF radio equipment, minimizing reflections when connectors are properly mated. The 7 m length facilitates separation between radio units and antennas or between transceiver and accessories without excessive signal loss in typical HF/VHF use.

Подходит для

• Соединение радиостанций и трансиверов с внешними антеннами
• Настольные и переносные радиостанции в диапазонах HF и VHF
• Лабораторные и учебные стенды для проверки антенн и приёмопередатчиков

Key specifications

• Impedance: 50 Ω
• Connectors: PL259 (male) to SO239 (female)
• Cable type: HF400 flexible coaxial
• Length: 7 m
• Frequency range: suitable for HF and VHF bands
• Construction: dielectric core with braided shield designed for flexibility

How to use

Attach the PL259 connector to the male socket of the transceiver or radio equipment and mate the SO239 connector to the matching jack on the antenna or accessory. Ensure connectors are firmly tightened by hand to secure the electrical connection and avoid over-torquing that could damage threads or center contacts. Route the cable to avoid tight bends and sharp edges; allow gentle curves consistent with the cable's flexibility to preserve shielding and impedance characteristics.

Usage recommendations

For best RF performance, inspect connectors for corrosion or dirt before use, keep cable runs as short and direct as practical for the installation, and avoid coiling large amounts of excess length near active equipment. When used outdoors temporarily, protect connector mating faces from moisture. For permanent outdoor installations, use a cable and connector assembly rated specifically for sustained environmental exposure.
