The HM300 is a free-standing, marine HF CB radio 1.6-30 MHz, heavy-duty 3-piece vertical radiator antenna, specifically designed for larger vessels or structure/tower installations. Please note a A-1429 heavy-duty deck mount base is recommended for ground/deck mounting. The HM300 HF vertical radiator antenna requires an A.T.U. to perform to stated performance levels. Performance and bandwidth will be determined by the function of your A.T.U. The 3-piece construction will require assembly, utilising basic hand tools of 52mm, 48mm, 30mm and 27mm spanners. Due to the size, weight and loading of the HM300 vertical radiator, please check the structural capacity of your structure or fixing location, and ensure adequate fixing of your mounting is achieved.
