Product code: HM300

Product Description

The HM300 is a free-standing, marine HF radio 3-30MHz, heavy-duty 3-piece vertical radiator, specifically designed for larger vessels or structure/tower installations. Please note a A-1429 heavy-duty deck mount base is required, or alternatively for wall mounting please request a A-1429-2 wall mount bracket. The HM300 vertical radiator requires an Automatic Tuning Unit or A.T.U. to both match as well as achieve the stated performance levels. Performance and bandwidith will be determined by the function of your A.T.U. Please note: The 3-piece construction will require assembly, utilising basic hand tools, threadlocker or equivalent can be applied to ferrule joins to reduce movement. 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. A regular maintenance check of your mounting hardware should be undertaken, as well as after any adverse weather.
