The K40 Black is a premium base-loaded CB antenna built to exacting tolerances using computer-designed components assembled on a fully automated production line — delivering consistent, repeatable performance that hand-assembled antennas simply can't match. Rated at 500W with a VSWR of 1.5:1 or better across 26–30 MHz, and supplied with a 17ft coax cable ready to connect to your mount. At 142cm it strikes a practical balance between performance and vehicle clearance, and the automated manufacturing process ensures every K40 performs identically — no variation between units. Please note: The K40 Black requires a separate magnetic mount or boot mount (such as the K40 M40) — not included.
