The AM 9144 from Schwarzbeck Mess-Elektronik OHG is a Height-Adjustable Telescopic Antenna Mast. It consists of a 3/8&rdquo male thread mast adapter, an interchangeable telescope in different lengths ranging from 0.56 to 3 m, a tiltable mast foot 1.5 m in diameter, wheels, and an extender to increase the height of the telescopic part further. This antenna positioner is made of GFK or fiberglass materials. Its modular design makes it possible to use different telescope parts that can be mounted on a stainless steel/low-reflective fiberglass mast foot, providing a secure stand and easy adjustment on uneven ground.
