Dish Alignment Angles: Azimuth ~ Elevation ~ LNBF Skew

Common questions: Where can I calculate the azimuth, elevation, and LNBF Skew for my dish?

If you can't find your city listed, just use your zip code. It will give you your location's Latitude & Longitude. Enter and click calculate.

On the Azimuth, remember to compensate for magnetic deviation for your area (see the USA map on the same page).

Also, LNBF tilt is very very important. The LNBF you are using might have an arrow on the top to indicate "TOP" or "0" tilt position. From that location you could turn it right or left to compensate for polarity skew at your area. This will make a huge difference in your Antenna Setup.

Basic 1 2 3 dish install:

1- Survey the area where to position the dish
2- The POLE must be vertical (+/- 1 degree is acceptable)
3- Point dish in Azimuth Direction
4- Adjust Elevation
5- Set LNBF Tilt.

Now for fine tuning and finding the signal:
1- If you are using the receiver and TV screen for signal meter, make sure you are using an active transponder on the satellite you are trying to lock on (i.e. 12177 or 111898 for Telstar 5)

2- Start by adjusting the Azimuth (right and left) until you get the quality. Peak it as high as possible. Make sure your other transponders are exhibiting a quality signal as well.

3- Now, start adjusting the Elevation up/down until you get a peaked signal. Tighten nuts/bolts.

4- Maximise signal by adjusting the LNBF Tilt (right or left 1 degree at a time).

5- Finally, maximise signal by adjusting the LNBF location in/out relative to the reflector. Tighten screw on LNBF collar.

If you use a BIRDOG, it will make your installation much easier, specially in high places.

The secret to using the Birdog is that,

1- You have to know the relative azimuth and elevation for your location.

2- You have to use the KUV & KUH settings for the satellite to maximize the signal

3- The Birdog works with standard type LNBFs only. It does not work with Universal type LNBFs (those require a 22kz tone that the Birdog does not produce).

Good luck to you all.

The above is your location's latitude and longitude and is not the dish azimuth/elevation.

When you click on calculate your Dish Elevation aand Azimuth are as follows:

Elevation: 28
Azimuth: 147 (Geographic). You have to subtract about 18 degrees to get the magnetic Azimuth.
LNBF Tilt: 21 Clockwise

Hat off to Sadoun for creating a forum. This is truly above and beyond what most dealer do! This includes all of the installation info on his web site also! I swear that he must be working 25 hours a day to do it all! (Snicker, Snicker). :wink:

Start another thread on "installation" section. Provide us more info about your gears. Fixed? H-H mount?......

Read this link below:
http://www.sadoun.com/Sat/Installati...stallation.htm
You have to set up the h-h mount correctly to get lock first before doing the scaning. Without locking on the any sats, doing the scaning will not get you any channels.

LNB

I want some clarifications on LNB and HH motore(rotors)

1) Can I use standard single LNB to connect more than one receiver.

2)What is the difference between LNB standard and LNB universal

3) What is the difference between:STAB HH 100 Motor and DiseqC 1.2 HH

Please Help I really need the answers.


Thank you

If you want each receiver to have independant control of the channels, you will need to use a dual outpt LNBF. If you want to watch the same channel (or same polarity channels), you can use a single LNBF connected to one receivers. The 2nd receiver is connected to the 1st receiver using the "loop out"

(Loop out connection is below LNB In)

Quote:
2)What is the difference between LNB standard and LNB universal
---------------------Standard----------- Universal
Freq Range:---- 11.2 - 12.2 GHz------10.7 - 12.75 Ghz
Lo Freq:--------- 10750 ------------ 9750,10600
22Khz tone:-------- Off---------------- Auto or ON

So as you can see, the universal LNB is better than the Standard in that: It covers more frequency. This allows you to receive channels from Atlantic satellites that utilize thouse lower frequencies.

Quote:
3) What is the difference between:STAB HH 100 Motor and DiseqC 1.2 HH
STAB HH100 and Satcontrol SM3D12 use both DiSEqC 1.2 and USALS (AKA DiSEqC 1.3)
While Motech uses only DiSEqC 1.2

USALS allows you to move the dish to the satellite much easier by just entering your Long/Latitude for your location and the motor will move and stop automatically (active response)

DiSEqC 1.2 is a PASSIVE. You have to move the dish manually east/west until you find the satellite.

Anyone else can explain this better maybe?

true south question

SG100 motor
Woburn, MA 01801
Lat 42
Magnatic inc angle = -16
would my true sounth be 180 - (-16) = 196 ?
Thanks

The apparent elevation of the dish is 15 or more degrees lower than it's actual receiving window. Have a look at this diagram.... it's easier to see it than it is to explain it....
So, if my elevation is listed at 46.9 degrees for DirecTV 101 in Savannah, GA, which of the following is true:

1) When I set my elevation to 46.9 the dish is actually pointing 15 degrees less than that..... or
2) The signal is actually coming in 15 degrees higher than this, at 61.9 degrees?

I need to know which is the correct line of sight because I have a lot of trees behind my house (looking south) and I am searching for a good mounting location. My options will increase dramatically if I am looking at the higher angles.

Thanks, Frank

Skew

The satellite calculator has a
LNBF polarization tilt (skew) value
I have an 18" DTV dish that I want to redirect to 82W, but there is no skew
on the mount, and I dont see any way to rotate the LNB, is it necessary to
set this skew on a circular LNB or is that value used with some other kind of setup.
I noticed there is a different skew for the DTV sats are the DTV LNBs hard set to
that skew.
Maybe I'm thinking too much into this.

Thanks for any help
Aaron

I believe that the skew is irrelevant on circular polarization . All you need to worry about is elevation.
