WTM Series – Winch Operated
WTM/1 and WTM/2
These masts will support large 3 element antennas providing that the maximum operating heights specified in this table are not exceeded. The figures are for a typical antenna with a boom length of 14 ft and element length of 27 ft giving wind loads of 100 Ibs at 80mph.
This mast is intended for smaller antennas where maximum height is of prime importance. It is particularly useful for experimental work and field strength measurement. However, if under extremely windy conditions the operating heights are reduced to those shown in the above table it will withstand the same wind loading as the WTM/2 mast.
This mast has been developed to withstand high head loads at heights of up to 29 ft. It will safely support a 2 ft diameter dish at a wind speed of 100 mph or a 3 ft diameter dish at a wind speed of 62 mph. It has a retracted length of only 9.78 ft making it ideally suitable for fitting to the rear of telecommunications vehicles. A 6.5 ft extension is available if required.
Due to the wide variety of applications and methods of mounting, the masts are manufactured as basic units. It is, therefore necessary when ordering to specify the type of mast, type of winch, mounting arrangement and accessories required.
