c band set up

Hello,

I am trying to set up my 2.3 meter C Band Dish with a actuator.

I was told that my c band and ku band dish settings are the same, now my settings are Elevation 27.5 and Declination 31.5.

Now i have set my Elevation angle to 27.5 but when i put a straight edge and inclometer on the back of the dish to set the Declination angle, the reading wont go near 31.5.

I have undone the nuts as far as they will go but cant get the angle of 31.5.

Am i doing something wrong ?

I live at Molendinar, Gold Coast.

Derek.

Have a read of this, and go to these websites.

You will be able to get the exact elevation & declination angles.
Seems like your declination is way to big!

Thanks for that kenny.

I have had a look at dishpointer.com but where you select the satellites, do i select the True North setting, Motorized setting ? or which one.

I do know my Elevation is 27.5 but cant work out the Declination angle !

Read FAQ here http://www.dishpointer.com/helpfaq/
What’s the difference between true azimuth and magnetic azimuth?

We all know that a compass points to the North – this is because the earth’s magnetic fields generally flow in that direction. But that’s not always the case. At many locations around the world, the flow deviates from that direction causing the compass to point not at the True North but at the Magnetic North. So for this reason, DishPointer calculates the geomagnetic flow field and the magnetic deviation for every place on earth, and then shows the magnetic azimuth in addition to the true azimuth – just in case you want to use a compass to align your dish.

This can also be quite handy when setting up a motorized dish as you will need to find True North or True South for the installation. Your compass will show you the magnetic North or South. Just take the difference between the true and magnetic azimuth to obtain the magnetic deviation and add that to the compass reading you get. Now align the satellite motor in that direction.

Hello Kenny;

I concur with your statement. One has to be aware of the agonic magnetic lines in ones area. In the extreme north of Canada, a compass will point south of true North. For Australia, one will get conflicting readings going east to west. Australia is relatively close to the South Magnetic Pole (SMP). Currently the SMP is directly south of Adelaide near the coastline of Antarctica. It is moving in a northwest direction by 10 to 15 kilometers per year.

Take care.

Additional Note:

Sometime in the future, Australia will be a great place to view the Southern Lights (Aurora Australis) as Australia will be very close to the SMP.

Enjoy the show.
