Hi
I’ve recently purchased a secondhand Channel Master 1.2m dish with polar mount and I need help in establishing the correct elevation. The polar mount isn’t a CM, but some other make/brand and there’s very little I can change on the polar mount apart from azimuth and elevation (see attachments). The scale on the polar mount ranges from 50 to 70 degrees and to be quite honest the point is useless.
The main satellite I’m interested in is Astra2D though I’ve tried setting up the dish towards Thor 2/3 1W that has an elevation requirement of 20°, but again no luck!
I know that CM has a reflector offset of 22.6°, so I’m assuming that the dish needs to be down tilted by some 2-5°…is this correct?
Thanks in advance,
Anthony
Based on my location (Stockholm) the set up should be as following:
Latitude: 59.4°
Longitude: 17.9°
Satellite orbit: 28.2E Astra 2A, 2B, 2C, 2D
Elevation: 22.0°
Azimuth (true): 168.0°
Azimuth (magn.): 164.1°
Polarisation tilt (deg): -6.04 (though for Astra satellites + 7 ) = 1.04°
Polar mount main axis angle (deg): 60°
Polar mount dish offset tilt (deg); 7.42
