The Diamond K412 is a professional, highly adjustable mobile antenna bracket engineered to provide a secure and clean installation point on passenger vehicles. Designed specifically for mounting onto sedan trunk lids, SUV back doors, utility tailgates, and hatchback doors, this premium bracket is the ideal choice for radio operators seeking a versatile, non-invasive installation. Despite its small, low-profile footprint, it delivers the legendary mechanical strength, reliability, and precision manufacturing that makes Diamond Antenna the global industry standard.
This model stands out with its advanced 3-axis articulation, allowing you to fine-tune your mobile antenna’s vertical alignment and tilt angle across three different planes. This extensive adjustability ensures that your antenna remains perfectly upright and optimally positioned for peak SWR performance and signal propagation, regardless of the vehicle’s curved contours or panel angles. Constructed from high-strength, corrosion-resistant alloy metals with a durable black finish, the K412 is engineered to withstand daily highway wind loads, car washes, and harsh outdoor weather conditions.
The K412 features a non-invasive, no-drill lip design that clamps securely onto any trunk or hatchback edge utilizing integrated Allen head set screws. This ensures a rock-solid physical connection and essential RF grounding to the chassis without damaging your vehicle’s paint or sheet metal. This SKU is supplied as the mount bracket only, without an integrated coaxial cable assembly, giving you complete freedom to pair it with your choice of standard mobile cable kits (such as PL-259 or NMO base cables, sold separately).
