The Pneumatic Hilomast - RM Series
The RM Series of Telescopic Hilomasts is operated by a ram, is robust in construction with a base tube diameter of 238mm and is intended for installation in vehicles.

Wind speeds in the aboue table are calculated for antennas or equipment with a side surface area of 11,600 sq. cms. (12.5 sq.ft.). The stress calculations and package dimensions are expedited by means of a computer, so it is a simple matter to design masts to exactly suit customers requirements. Retracted length of masts may increase by up to 76mm. depending on head load.
