The Antenna must be set up and aligned correctly to
receive signals from satellites in geostationary orbit. Find hereby
following instructions for best result:
A. Position the ground or wall support tube - Item 1, such as the vertical
section is upright to a tolerance of +/- 0.25°. A clinometer
should be used for this purpose. B.
Attach the antenna to the polar mount and secure - care to be taken to ensure
that the reflector is not deformed. C.
Position the antenna exactly facing due south to by rotating the complete
assembly about the vertical tube. At this point check the reflector is square - that is 90° with the mount - see
Fig. 1. You may need to achieve squareness by
adjusting either the manual or motorised actuator -
Item 2 (optional) For this purpose a simple measure can be used to check the dimension between
the reflector attachment points (A) on the horizontal member and the actuator
pick up points (B) on the centre tube.
Having achieved squareness and due south, lock the
assembly securely to the vertical tube using the clamp bolts provided - Item
3. D.
Check your location and note the latitude. Using the chart -
Fig. 2, set the
"mount axis angle" as stated using the threaded
adjuster - Item 4. Use a clinometer for accuracy. E. Again using the chart - Fig. 2, set the declination angle. Use threaded
adjuster - Item 5 - to create correct the angle between the mount axis member
and the plane across the face of the reflector. Here simple add the declination angle to the mount axis angle and check
using the clinometer on the front face of the reflector rim. Do not use
adjuster - Item 4, only use Item 5 for this final setting. F. Check all 3 settings and secure all fixings. G.
Using the manual or motorised actuator, Item 2 (optional), drive the
antenna around the arc and if using the motorised actuator, set the limits to
prevent damage to the reflector from adjacent obstacles.
