Angles, degrees, etc. - Techwatch: Satellite TV forums, FTA, Cable, Hardware, & Tech forums

I have been working out where to point my dish (when it all arrives in about 2 or three days), I understand the position(s) of the Sats on the Equator (or nearly so), nad have had a look at the astra Installation site which works out the azimuth etc. for you.

But how can I work out the same for others like Hotbird at 13E ? Is there a bit of software I can download or do I have to dig out my slide rule?

Thanks, Geoff

Its quite simple really hallii, the angles are literally that. 13E is 28.2-13 = 15.2 degrees west of 28.2. So you just need a protractor to get the approximate position.

From your earlier posts, you appeared to be thinking in terms of a fixed dish with monobloc lnb. That wont work for satellites as far apart as 28.2E and 13E. You would either have to move your dish or have it motorised, or have separate lnbs.

In addition to swinging around from one angle to the other, the dish elevation also need to change. Highest at due south and lowest and extreme east and west. A motorised mount automatically takes care of the elevation change as the dish swings around.

No, I went for a single LNB and will rotate it as required by hand, the prime purpose is for camping reception abroad, hence the need to be able to know where to point the dish.

I had a look here and now I am really confused! http://www.satsig.net/ssazelm.htm

That website does make it seem complicated doesn't it.

Have a read of some of STICK's guides. They are more straightforward.

Also, the SMW utility listed in our Utilities section is one of the best beginners tools to use. Really simple, with none of the twiddly bits you don't need.

You'll find that after a few tries, you'll be able to find most major satellites with your eyes shut, especially when it's cold or raining
