TELSAT® COMMUNICATIONS LTD

Installed at embassies and broadcasting facilities around the world.

Available in Fixed Mount (non motorised) and
Dual Axis horizon-to-horizon / motorised declination models.

Unique hub design allows rotation of the antenna during assembly,
making it possible to assemble the reflector on the tower.
 
Antenna mount and reflector may also be assembled on the ground
and then raised up to the tower by a crane.   

Other features include:

A STURDY STEEL TOWER CONSISTING OF ACENTRAL 5-9/16 INCH O.D. PIPE, FOUR GUSSETED, STEEL TUBE LEGS AND DIAGONAL BRACING ANCHORED IN A CONCRETE PAD. 

A STEEL HUB RING CONSISTING OF A HEAVY OUTER RING AND TWELVE SPOKES ARE ATTACHED TO THE ANTENNA'S CORE OR SPOOL.  THE ANTENNA PIVOTS ON THIS RING AND PROVIDES SUPPORT FORTHE TRUSSES.

HORIZON-TO-HORIZON AZIMUTH MOVEMENT IS PROVIDED BY A DOUBLE CHAIN-DRIVEN STEEL D-RING.  THE CHAIN IS DRIVEN BY A 36 VOLT D.C. MOTOR.

MOTORIZED DECLINATION MOVEMENT ALLOWS EASY DECLINATION ADJUSTMENT.   MOTORIZED DECLINATION IS SUPERIOR TO MOTORIZED ELEVATION MOVEMENT IN THAT IT KEEPS THE ANTENNA PERPENDICULAR TO THE CLARKE SATELLITE BELT.  THIS MAKES IT EASIER TO FIND AND TRACK SATELLITES.

DUAL AXIS TRACKING IS A STANDARD FUNCTION ON THE MOTORIZED MODEL. THIS ALLOWS CONTINUOUS RECEPTION OF INCLINED ORBIT SATELLITES, USING AN OPTIONAL COMMERCIAL CONTROLLER ASSEMBLY.

A PRECISION, MACHINED SPOOL FUNCTIONS AS THE CORE OF THE ANTENNA. THE TRUSSES ARE ATTACHED TO THE SPOOL IN SUCH A WAY AS TO ALLOW THE SPOOL TO TURN ON THE MOUNT DURING REFLECTOR ASSEMBLY.  THIS ALLOWS ASSEMBLY OF THE REFLECTOR AFTER THE MOUNT HAS BEEN ASSEMBLED ON THETOWER.  THIS CAN BE DONE WITHOUT THE USE OF A CRANE;  AN EXTREMELY USEFUL FEATURE INREMOTE AREAS.

GREASABLE, SELF ALIGNING BEARINGS ARE USED FOR THE AZIMUTH PIVOT BEARINGS.  DECLINATION BEARINGS ARE OIL IMPREGNATED BRONZE.

16 WELDED ALUMINUM TRUSSES, MADE UP OF TWO MATCHED PARTS, SUPPORT THEREFLECTOR.

9 SETS OF ALUMINUM MESH RINGS, 16 TO A SET, ARE BOLTED BETWEEN ADJACENT TRUSSES.  THE MESH PANELS ARE THEN ATTACHED TO THE RINGS WITH STAINLESS STEEL HOOKS.  THESE RINGS ALSO HELP SUPPORT THE ANTENNA AND MAINTAIN PARABOLIC ACCURACY.

ALUMINUM, PRE-PUNCHED STRIPS ARE SCREWED OVER THE TOP OF THE MESH PANELSAND INTO EACH TRUSS.   THESE STRIPS AND THE ALUMINUM MESH TRIP, WHICH CLAMPS AROUND THE ANTENNA'S PERIMETER, HOLD THE MESH SECURELY IN PLACE.

A QUAD FEED SUPPORT AND CENTER PLATE PRECISELY CENTER THE FEED AND ADDSTRENGTH AND STABILITY TO THE ANTENNA.

A GALVANIZED COATING PROTECTS ALL STEEL PARTS OF THE ANTENNA.  MESHPANELS ARE BLACK POWDER COATED.  DACROMET HARDWARE IS INCLUDED TO PROVIDE A MEASURE OF CORROSION RESISTANCE.  ALL OTHER PARTS ARE MILL FINISHED ALUMINUM.

A 5-YEAR LIMITED WARRANTY COVERS THE T-24 ANTENNA.
