MOOKEERF Dual CB Antenna Coax Cable 18ft RG8X

MOOKEERF Dual CB Antenna Coax Cable 18FT is an ultra low-loss RG8X coax assembly with a stranded copper core and three PL-259 connectors designed to hook two CB or ham antennas to one transceiver reliably.

This 18-foot dual CB coax cable delivers a balanced mix of signal protection, flexibility, and rugged outdoor durability for mobile and fixed radio setups. Built on the compact RG8X (mini-8) form factor, the cable pairs a stranded pure-copper conductor with dual shielding and a waterproof FEP jacket to minimize signal loss, resist EMI/RFI, and withstand weather exposure. The assembly includes three reinforced PL-259 male connectors and an extended heat-shrink sleeve at each termination for stronger strain relief.

How does this cable reduce signal loss compared with generic coax?

MOOKEERF's RG8X design prioritizes low insertion loss through a pure copper stranded center conductor and dual outer shields: aluminum foil plus a tinned copper braid. Together they maintain high shielding effectiveness and lower attenuation across CB and nearby HF frequencies.

• Stranded pure copper center improves conductivity and flexibility.
• Foil + tinned-copper braid exceeds 95% shielding efficiency.
• Engineered for lower loss over 18 feet versus basic RG58-style cable.

Is the cable durable enough for outdoor and vehicle use?

The outer jacket is FEP-rated to resist moisture, UV exposure, and abrasion, making the cable suitable for permanent outdoor runs or mobile installations on trucks and RVs. Connectors are soldered and fitted with extended heat-shrink tubes to reduce strain at the terminations.

• Waterproof FEP jacket stands up to rain and sunlight.
• 2.2-inch heat-shrink at each PL-259 provides improved connector support.
• Robust soldered PL-259s reduce the chance of separation under vibration.

How do the three PL-259 connectors work for a dual-antenna setup?

The cable is configured so one end connects to your transceiver and the remaining two PL-259s attach to two separate CB or amateur radio antenna feeds. This lets you run twin antennas or use a co-phasing arrangement without additional adapters or extra coax runs.

• One transceiver feed and two antenna terminations—plug-and-play simplicity.
• Saves space and routing complexity compared with two separate coax runs.
• Compatible with standard PL-259/SO-239 interfaces used on most CB/ham equipment.

Will this cable be easy to route and install in tight or mobile spaces?

The stranded center conductor and relatively slim RG8X diameter make the cable much more flexible than larger, solid-core coax types. It bends easily around corners and through vehicle pass-throughs, simplifying installations where space is limited.

• Stranded core increases bendability for neat routing.
• 18-foot length covers most mobile and yard antenna placements without extra splices.
• Lightweight compared with heavier RG8 variants, easing mounting and tie-downs.

Who this cable is for: This MOOKEERF 18FT RG8X dual coax assembly suits CB radio users, amateur radio operators, truckers, and RV owners who want a practical, weather-resistant way to connect two antennas to a single transceiver. It's aimed at installers who value low loss, high shielding, and flexible routing in both mobile and permanent antenna systems. If you need a compact, dependable coax solution with built-in PL-259 terminations and enhanced strain relief for outdoor use, this cable is a practical choice.
