Andrew LDF4-50A – 1/2″ Foam Heliax 50 Ohm Coax Cable

NB. Priced per metre

Andrew LDF4-50A is a premium 1/2″ HELIAX low density foam 50 Ω coaxial cable designed for demanding RF feeder applications where low loss, high power handling and long-term reliability are critical. Its corrugated copper outer conductor, foam PE dielectric and rugged black PE jacket make it ideal for tower, rooftop and shelter installations in professional broadcast and telecom sites.

Key features

• 1/2″ HELIAX low loss 50 Ω coaxial cable with low density foam dielectric for excellent electrical performance.
• Corrugated copper outer conductor and copper-clad aluminium inner conductor for high shielding effectiveness and mechanical strength.
• Wide operating band from 1 to 8,800 MHz with low attenuation, supporting FM, VHF, UHF, microwave and cellular services.
• High power capability with multi-kilowatt average ratings at HF/VHF and up to 40 kW peak power under standard conditions.
• Robust UV and weather resistant black PE jacket for long outdoor life on masts, towers and building runs.
• Compact 1/2″ form factor and tight minimum bend radius for easier routing in crowded cable ladders and entry panels.

Typical applications

• Main feeder between transmitters and antennas in FM, AM, VHF, UHF and DAB broadcast systems.
• Base station and repeater sites where low attenuation and stable impedance are required over long runs.
• Professional two-way radio, telemetry and RF distribution networks needing rugged outdoor hardline cable.

Suggested accessories and alternatives

For a complete installation, pair this cable with the
Andrew L4DM-F 7-16 DIN Male Connector for LDF4-50A
and the versatile
Andrew Grounding Kit
to ensure proper terminations and lightning protection. Where a larger diameter feeder is required, consider the
Andrew AVA5-50 HELIAX 7/8″ Coaxial Cable
for even lower loss on very long runs.
