100 Foot UHF PL259 Male to UHF PL259 Male LMR400 Coax - Low Loss

In this review the 100 ft UHF PL259 male to UHF PL259 male LMR400 coax is assessed for installers, ham radio operators, and anyone needing a long, low loss antenna feeder. The bottom line: this cable is a practical drop-in replacement for RG-8/9913 where flexibility and reduced signal loss matter, and it stands out for its durable PE jacket and superior shielding. For short to medium antenna runs or jumper assemblies in wireless systems, it offers a reliable balance of bendability, low attenuation, and robust construction.

Key Features

• Drop-in Replacement: Replaces RG-8/9913 air-dielectric cable without changing connector practices, making upgrades straightforward.
• Low Loss Performance: LMR400 delivers lower attenuation than other flexible cables of similar size, improving signal strength over distance.
• Flexibility and Bendability: The flexible outer conductor allows tighter bend radii, which helps route cable in constrained installations.
• Rugged Jacket: The PE outer jacket provides abrasion resistance for outdoor or exposed runs and extended handling.
• Strong RF Shielding: Multi-ply bonded foil shielding gives far better isolation than single-shield coax, reducing interference between adjacent runs.
• Standard Connectors: Fitted with two UHF PL259 male connectors for common ham, CB, and antenna hardware compatibility.

Who It's For

This cable is ideal for ham radio operators, WLAN and WiFi installers, and CB radio users who need a long, low loss feedline that is still flexible enough to route around obstacles. It suits jumper assemblies and short to medium antenna feeder runs where improved shielding and abrasion resistance are important.

It is less appropriate for ultra-long backbone runs demanding hard-line semirigid cable where lowest possible loss per foot is critical, or for installations that require connectors other than UHF PL259 without modification.

Pros & Cons

Pros

• Low loss compared with similar flexible coax, which preserves signal for WiFi, cellular, and HF/UHF/VHF uses.
• Excellent flexibility that eases routing in tight spaces and around mounting structures.
• Durable PE jacket and multi-ply shield offer good outdoor durability and interference protection.

Cons

• Comes with UHF PL259 male connectors only, so other connector types require adapter or re-termination.
• For very long runs where absolute minimum loss is needed, a hard-line solution may be preferable.

Our Verdict

The 100 ft LMR400 coax is a sensible choice for hobbyists and installers who need a flexible, low loss 50 Ohm feedline with robust shielding and a tough jacket. It represents good value for medium-length antenna runs and jumper assemblies, especially where easy routing and abrasion resistance matter; just plan for connectors if you need a different interface.

Frequently Asked Questions

Is this cable suitable for ham radio antenna feeds?
Yes. The LMR400 is designed for HF/UHF/VHF installations and performs well up to hundreds of feet, with excellent shielding and low loss for typical ham use.

Will the PL259 connectors fit my equipment?
The cable ships with UHF PL259 male connectors, which fit most ham and CB radios; if you need other connector types, you can adapt or re-terminate the cable.

Can this cable be used outdoors?
Yes. The PE jacket is abrasion resistant and suitable for exposed runs, though standard weatherproofing at connectors is recommended.
