Diamond KB144R2 Yagi Side Mount Bracket For A144S5 & A144S10

The Diamond KB144R2 is a genuine support boom bracket for side-mounting VHF and UHF Yagi antennas in vertical polarisation applications. By offsetting the antenna boom away from the mast, it minimises mast interaction and radiation pattern distortion — preserving gain, front-to-back ratio, and pattern symmetry that would otherwise be compromised when a Yagi is mounted directly against a conductive mast. Heavy-duty aluminium construction with a reinforced truss-style support arm. Supports mast diameters up to 1.75" (44.5mm). Suitable for Diamond Yagi antennas including the A144S5 and A144S10, and ideal for FM, repeater, and vertically polarised communications installations. Please note: Mast shown in product images is for demonstration purposes only and is not included.
