TELESCOPIC WINCH OPERATED MASTS SERIES STVDESIGNED FOR HARSHEST MILITARY ENVIRONMENT OPERATIONS

Telescopic winch operated masts series are designed on a basis of many years of experience inSTVdevelopment and production of antennas and antenna masts and on a basis of knowing and consideringthe needs and demands of the end users in the era of modern wireless telecommunications.

The family of telescopic masts STV consists carefully selected modern materials and technologies andconsiderate design, functionality and simplicity of use. With all that featuresthe family of the masts STV are suitable for use on the field as well as on thevehicles also in hardest environmental conditions.

The mast is basically composed of telescopic sections made of compositematerial ("fiberglass") by use the process of "pultrusion". By use of thattechnology all the fibres are placed longitudinally along the section enableexcellent stability with high degree of elasticity. Certain fiberglass layer is alsowounded radially during the pultrusion process enables high degree of radialhardness. The masts STV meet environmental requirements in accordancewith .MIL-STD-810

The sections have four special placed equally outsidelongitudinal guidwaysand made during the process of pultrusion enable excellent guidance whenraising and lowering of the masts as well as additionally longitudinal stability.The guidways ensure that the mast is prevent theaxially joined togethervarious sections from turning which allows us to easily turn the whole mast inthe case of using directional antennas. On the end of the sections are specialslide-joints made of durable polyacetal with low weight and excellentmechanical characteristics.

Erection of the mast is enabled with withremovable hand operated winchcogwheel transmission and with system of strong polyester-aramide reinforcedbelts guided between the sections. During the erection we put the belt into thewinch wheel and wind it with crank arm, which lifts the sections up. Forlowering the mast we simply turn the crank arm in the opposite directionwithout any need of hand switching which is done by built-in automaticswitch mechanism automatic safety brake. The winch has built-in to protectthe operator in the case of heavier loads.

The telescopic mast STV has all accessories need for field erection: anchors,guying ropes (made of DYNEEMA material), hammer, etc., together withspecial cross-bar with eye-anchor intended to fix the mast in specific direction,the base plate with safety chain attachments and extension aluminum tubewith grounding screw for antenna attachment. All the accessories are stored inseparate linen bags. The mast alone has also linen cap for top sectionsprotection.

The telescopic masts series STV are applicable also for mobile usemounted on vehicles. For this purpose a special mounting kit is available,composed of base plate element and side bracket.

STV TELESCOPIC MASTS - MOBILE MOUNTING

STV telescopic winch driven masts could be mounted on various kinds of vehicles.To ensure that the mast will be mounted properly and safely, the following factsmust be taken into account:

- Two basic mobilemounting adapters areavailable: the STV-L andSTV-U (detailed technicaldrawings are available onrequest). Both adaptershave all necessary holesand fittings made so thatthe masts series STV couldbe inserted on that adapterswith the mast foot and thefirst guying ring plate.

- The other side of theadapters has another holes drilled and preparedto fit on special mounting bracket (not supplied!)which will fit specific car body. The user mustprovide those adapters according to the specificvehicle body construction.

STV TELESCOPIC MASTS - SEMI MOBILEMOUNTING

When the mast is too big to be completely attached to thevehicle or shelter then so called "semi mobile" mounting isrecommended. In this case the mast foot lays on the groundwhile to upper attachment can be provided with variouscombinations of clamps and consoles available.
