What Is the Terminator Connector?
The Terminator is Cobra's quick-attach connector that makes radio-to-coax installation faster and more secure than traditional threaded fittings — a firm, positive connection that resists loosening from road vibration, especially handy in hard-to-reach behind-dash installs.
How to Install the Cobra 18 ft CB Coax Kit
Route the 18 ft cable from your radio location to the antenna mount.
Attach the Terminator end to the radio — the positive-lock design seats quickly.
Connect the PL-259 end to your antenna or mount.
Avoid pinch points and ignition wiring; hand-tighten all fittings.
Check SWR on channels 1, 20, and 40 to verify installation.
Is 18 ft Coax Better for CB Radio?
Yes — 18 ft is the mobile standard. It provides enough length for routing in trucks and Jeeps while keeping RG-58 signal loss negligible for typical 4-watt CB power.

Terminator makes hookup painless
The quick-attach connector is honestly the best part — took me two minutes to get my antenna hooked up with no tools. Signal is clean and SWR checked out low right away.

Convenient and well built
I've wired plenty of CB setups over the years and the Terminator design saves real time. The cable is thick and the connection feels secure once locked in. Only wish the cable were a touch more flexible for tight routing, but performance-wise it's great.

Good but pricey without the sale
At full price I'd probably pass, but at half off it's a fair deal. Signal quality is good and the quick connector is genuinely handy for swapping antennas between vehicles.
