Telescopic Antenna Masts

 

EXB Series

ProphetEXB telescopic masts are designed for highly mobile operations (such as battlefield communications and electronic warfare) where minimal time and man-power for deployment is available. These telescoping masts are push-button, vehicle- mounted mast systems are designed for rapid extension and operation without guy ropes. They are designed to extend to heights up to 46 ft (payload height at 49 ft above ground when vehicle mounted) with maximum payloads of up to 242 pounds.  Depending on mast top maximum deflection requirements, EXB-masts utilize composite tube sections varying from pure glass fiber to pure carbon fiber. EXB telescoping masts are extended and retracted utilizing hoisting belts driven by a winch. This is an effective, well-proven technique which is more reliable under severe operating conditions (especially sand and dust). EXB-masts have a double-belt system - one belt is used for mast extension, the second belt is used to provide positive retraction to assure proper operation under adverse conditions of wind and slope. EXB-masts are equipped with an automatic latch mechanism for controlling the order in which tube sections extend. The winch is operated by an electric Winch Power Unit (WPU) with remote control, with WPU versions available for either AC or DC power supplies.  A manual hand crank is provided as a back-up for power failure.

EXB telescopic masts can be supplied in CARC finish, color as specified by the customer.
