True south?? - Techwatch: Satellite TV forums, FTA, Cable, Hardware, & Tech forums

I want to set my new dish initially to true south. What angle do i need to add/subtract from my magnetic south? I live in manchester at:

Latitude = 53.4348, Longitude = -2.2750

I have tried www.satsig.net and that suggests a azimuth of 181.2(magnetic) but on http://www.ngdc.noaa.gov/seg/geomag/...alcDeclination this suggests 3degrees

thanks

Your magnetic variation is around three and a half degrees - the same (and in the same direction) as the chap who started this thread.

So im i correct in thinking, point my dish at magnetic south on the comapass and then trn it an extra 3 degrees towards east or towards west?

thanks for the help
