The MT-3000A is an extremley reliable, heavy duty motorized elevation unit designed for elevating large arrays of VHF or UHF antennas.In most applications the unit provides a full 180 degrees of rotation, which means the aray can be completely inverted for ease of assembly, dissassembly and maintenance of the upper bays. The final drive ratio is a powerful 19307:1 producing 4500 in/lbs of torque for smooth, controlled and consistent movement. A magentically acutated reed switch mounted to the motor shaft provides pulses ofr readout and control functions of M2's progrommable control units.
The MT3000A accepts round "H" frame crossbooms from 3" up to 5". Larger diameters and triangular tower sections can also be used with optional mounting brackets, although towers may limit rotation to less than 180 degrees. The unit mouts to 2" and 3" masts with larger sizes accommodated by special order. Masts can extend above the unit but will limit rotation.
The MT3000A features heavy welded steel construction and is gold zinc plated. The 24" diamter drive gear is chain driven by a rugged, outdoor-duty motor and gear box assembly. A 9 tooth #40 sprocket mounts to the 3/4" diameter double bearing supported output shaft and through two idler sprockets which drive a #40 chain attached to both ends of the main drive gear.
