Composite FiberglassMK112 Heavy Duty Guyed Mast
HD Base Mast Kit
For Fixed Base Use
NVIS and Inverted Vee
Barker & Williamson's MK112 heavy duty base fiberglass mast systems provide a reliable means of supporting our broadband antennas in permanent locations from the ground. Configurations are available for both NVIS and long range use.
Mast poles are made in 6 foot sections. They are easily assembled with an inner joiner, and bolted together. A locator pin is hammered into the ground to stabilize the bottom of the assembly. Polyester guy lines are provided, which won't stretch, rot, or degrade in UV. Aluminum ground stakes are included which won't corrode.
The material utilized for the pole sections is a composite known as FRP - fiberglass reinforced plastic. Unlike cheap "fishing pole" material it is extremely lightweight, strong, and rigid. The light green color is throughout the material - no chipping paint. Also, shock hazards are eliminated.
These mast kits are designed to support all of our broadband antennas. They may also be used to support various other antennas. Please check with the factory for intended usage.
These kits have 6 Ft mast sections which are bolted together - no pins or lanyards on these models. All mast tops have a halyard pulley. Kits DO NOT include carry bags.
