XRDS -RF CB Coax Cable 150FT LMR400 PL-259 - Low Loss Outdoor Cable

In this review the XRDS -RF 150FT LMR400 CB coax cable is evaluated for serious CB, ham and marine users who need a long, low-loss feedline. The bottom line is straightforward: it is best for installations where signal retention over distance and a weatherproof connection matter most. The review found the larger 0.41 in conductor and copper clad aluminium construction deliver noticeably lower loss than thinner RG58-type cables, while the nickel-plated PL-259 clamp connectors and adhesive-lined heat shrink provide a secure, weather-resistant termination for outdoor use.

Key Features

• Ultra-low loss conductor: The 0.41 in copper clad aluminium center conductor keeps signal loss down over long runs compared with smaller RG58 or 240 type cables, which matters for weak-signal use.
• Durable jacket: The flexible UV-proof RF-PVC jacket is designed for long outdoor exposure and helps the cable survive roof- and mast-mounted antenna installations.
• Secure PL-259 clamp connector: The cable uses a mount clamp PL-259 rather than a simple crimp type, improving mechanical retention and reducing the chance of connector failure.
• Nickel-plated waterproof connectors: New nickel-plated UHF connectors resist corrosion in marine and coastal environments, improving long-term reliability.
• Adhesive-lined heat shrink: The extended 2.2 in black heat shrink with adhesive lining seals the connector joint and helps keep moisture out of the cable end.
• Wide compatibility: Works with CB radios, ham gear, VHF/UHF setups, SWR meters, scanners and antenna analyzers, making it a versatile feedline.

Who It's For

The XRDS -RF 150FT LMR400 cable is aimed at CB and amateur radio operators, boat owners using marine radio or AIS, and anyone needing a long outdoor feedline with reduced loss compared with thinner coax types. Installers who prioritize a weatherproof connection and a robust connector will appreciate the clamp-style PL-259 and adhesive-lined heat shrink.

It may be less suitable for those who need extreme flexibility for tight or internal cable routing, or for very short indoor runs where the stiffness and larger diameter are unnecessary. If you want a low-profile, ultra-flexible jumper for internal connections, a smaller coax might be a better fit.

Pros & Cons

Pros

• Low loss over long runs thanks to the larger 0.41 in copper clad aluminium conductor.
• Weather-resistant design with UV-proof RF-PVC jacket and adhesive-lined heat shrink for sealed terminations.
• Secure nickel-plated PL-259 clamp connectors reduce the risk of connector separation or corrosion in outdoor use.

Cons

• Some users report mixed impressions of stiffness; the thicker cable can feel less flexible in tight installations.
• Heavier and bulkier than RG58-type cable, which can complicate routing in cramped runs.

Frequently Asked Questions

Is this cable suitable for marine use?
Yes. The UV-proof jacket, nickel-plated connectors and adhesive-lined heat shrink make it suitable for marine and coastal antenna installations.

Does the cable come with connectors attached?
The product is supplied with nickel-plated PL-259 clamp mount UHF male connectors assembled and sealed with adhesive-lined heat shrink for a secure termination.

How does loss compare to RG58?
Because of the larger 0.41 in conductor and LMR400 construction, this cable shows noticeably lower loss than RG58 or 240-type coax over long runs, which preserves more signal at the antenna.
