For Fixed Roof Top Use

Permanent Mounting
NVIS and Inverted Vee
Heavy Duty Pole
24 Ft Heavy Duty Base Mast Kit
Barker & Williamson's MK112 heavy duty base fiberglass mast systems provide a reliable means of supporting our broadband antennas in a permanent roof top application.   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 special foot is provided for roof top installations which is usable with flat, sloped, or peaked applications.   Polyester guy lines are provided, which won't stretch, rot, or degrade in UV.

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.

Part Number Selection

These masts come several different ways.  Please read carefully to make the proper selection for your intended use.  These are not intended for permanent base uses - utilize the MK112 series instead.
