Dual CB Antenna Coax Cable 20FT Low Loss RG8X with 3 PL-259 Connectors

In this review of the Dual CB Antenna Coax Cable 20FT, the bottom line is simple: this cable is for radio operators who need a flexible, low-loss run for linking two CB or ham antennas to one transceiver. The reviewer found the stranded pure copper center and double shielding delivered consistently low signal degradation over longer runs, while the waterproof FEP jacket and reinforced PL-259 terminations provided practical durability for outdoor use. If you want reliable signal transfer with the option to hook up two antennas to one radio, this cable is an efficient, workmanlike choice.

Key Features

• Ultra low loss: Double shielding and a pure copper inner conductor reduce signal leakage and help preserve signal strength over a 20 ft run.
• Premium materials: Stranded pure copper center and aluminum foil plus tinned copper braid deliver over 95% shielding against EMI and RFI for cleaner reception.
• Flexibility: The stranded core makes the RG8X cable noticeably easier to route through tight bends and around equipment than solid conductor types.
• Durable connectors: Three PL-259 male connectors with extended heat shrink provide a stronger mechanical join that resists pulling and separation.
• Outdoor rated jacket: Waterproof FEP outer jacket protects the cable from weather exposure when installed on masts or in exterior routing.

Who It's For

This cable suits CB and amateur radio operators who need a 20 ft dual feed coax to combine or switch two twin antennas into a single transceiver, especially when low loss and weather resistance matter. It is useful for base stations, mobile mast setups, and temporary field installations where cable flexibility and connector durability simplify installation.

Users who require extra-long runs beyond 20 ft, specialty impedance or connector types other than PL-259, or factory-assembled solderless quick-disconnect solutions should consider other options. Also, those who prefer a heavier RG58 or full-size RG8 for specific power handling needs may look elsewhere.

Pros & Cons

Pros

• Low-loss performance from pure copper conductor and double shielding helps maintain signal quality over distance.
• Stranded center conductor delivers better flex and easier routing than solid-core mini-8 alternatives.
• Waterproof FEP jacket and upgraded heat shrink at PL-259 terminations improve outdoor durability and connector retention.

Cons

• At 20 ft length it may be short for installations needing significantly longer runs without additional connectors.
• The cable is a mini-8 (RG8X) size, which may not match every high-power installation that prefers larger-diameter coax.
