View Full Version : Southern *C Install ?'s

11-21-2003, 03:09 PM
Any help will be apriciated /forums/images/graemlins/wink.gif

I am going to install a Starchoice DSr-500 and a 76cm oval dish for my in-laws in their new house, here in Southeastern Pennsylvania. Is there a installation manual available on-line so I am ahead of the game before I get over there. I have installed many Directv's and Dishnetwork's and my own Bell, but I here this is totally different.

Ok, next question. How do I figure out a skew for this. Here is our location.
40.32989 N
75.944188 W

And finally is there a owners manual or something online I could download so I am familiar with DSR-500 before hand?

For Pittsburgh on F1

AZ=218.5 EL=35.5 Skew=118.5

AZ is true. You will have to compensate for magnetic deviation which I believe will result in 227.4

Hmmm...well, as long as we're asking /forums/images/graemlins/smile.gif ... what kind of skew would one use in Austin, Texas? And how could I go about calculating this number?

You may not need to calculate skew at this moment.... Skew is for dual sat reception and you're a little bit too much to the south in Austin to see E2R (see below). Aim for F1 to maximise reception. You can always re-adjust your dish next August when Anik F2 goes into service and replaces Anik E2R.

Skew is still very important when using Starchoice even for single satellite reception...

If the sku is out a lot they won't get anything...and it should be adjusted with as much care an detail as the elevation and compass headings...

Oh yes... how quickly one forgets /forums/images/graemlins/frown.gif ... I forgot that you used to have to rotate the LNB on the old round dish too.

DBS (i.e. DISH, DirecTV, Bev) dishes with circular polarities only need to worry about skew when multiple sat reception is needed.

Well when I use a sat finding calculator I come up with the following:

107.3sat 33.4el 234.3az +31.5skew
111.1sat 31.1el 238.5az +34.2skew

So I assume I go in the middle of everything and make the following settings.

Set the skew at 32.9 wich would make in 129.9
Azmuth of 236.4 and an elevation of 32.3

Does this sound right? or does the dish need to be aimed at just one satellite to pick up both?

Austin TX for F1

AZ= 198.4

Sat B E2

AZ= 205.1
EL= 51.8
Skew= 111.6

Back in my *C days and with the older LNBs, you used to aim directly at the weaker E2(R) at 107. The F1 LNB was offset slightly from the focal point.

What kind of dish/LNB do you have (after, I think *C only has about 42 different dish/LNB configurations /forums/images/graemlins/laugh.gif )

Even with the newer quad lnbf's, the pointing is the same.

This is a 76cm quad lnbf, so I should point it at the 107.3 satellite when aiming. But what about the elevation and skew should I use the numbers I came up with or the numbers for just 107.3 itself?

Adjust dish to Sat B coordinates.
Sat A is F1 and Sat B is E2.

For Reading PA:

True AZ = 227.4
EL = 31.1
Skew = 124.4

I believe the coordinates I gave at the beginning of the thread were for Sat A in Pittsburgh.
