The XT Series are Clark's "HIGH POWER" telescopic masts with the capability of lifting 150 kilograms (special versions to 300 Kg can be supplied) to 10 metres or 36 kg to 18 metres (special versions to 30 metres & 50 Kg headload capability can be supplied).
As a member of Clark's Phase 2 series, they also have the un-guyed rigidity which has become increasingly necessary for today's equipment, particularly when microwave dish antennas are used. Electronic News Gathering, Line of Sight Links, small Radars, surveillance equipment of all kinds, portable phone cells, these are the applications in which XT masts perform best.
The 203 mm (8 inch) base section diameter makes the mast too large to set up manually. In almost all cases they are built into or onto vehicles or shelters in the vertical position. The top of each mast is provided with a substantial flange for the attachment of large headloads. Each mast section may be optionally factory fitted with locking (combined) collars for semi-permanent erection if desired, allowing the mast to remain extended without an air supply for long periods of time. For minimum retracted height the Plain (non-locking) Collar version may be ordered.
When the XT mast is fully extended a locking key system gives high torsional strength. To increase the stability of headloads with large wind area in high wind conditions, Guys may be attached to optional factory fitted Guy Collars. However the real advantage of the XT masts is their unguyed stability for work in average wind conditions.
A range of mounting and guying Accessories are available for the Clark Masts XT Series. Also a number of Air Supply options are available, including Hand Pumps, 12/24 Volt DC and 230/110 Volt AC Controller/Compressors, Petrol powered compressors and accessories to allow a vehicle's air source to be used.
All of these qualities give the XT mast series equal suitability for use in civilian and military applications, as evidenced by its choice for the advanced Verdi-2 Military Reconnaissance vehicle shown below.
For applications where a heavy duty mast and very rapid deployment is required, Clark
Masts' 804 Heavy Duty Trailer Mast Series offer XT masts trailer mounted ready for fast turn
around operations.

The photo at left is of an XT18, (an 18 metre mast with 60 Kg headload capability) and gives an ideal of the scale of the XT Series. Although they are normally vehicle mounted they may also be trailer or shelter mounted. Furthermore, longevity has always been a byword for Clark Masts. Many customers still operate masts 30-40 years old and are able to keep them in perfect order with readily available spares when necessary.
