Free To Air Installation Guide

A. Pre-Installation Homework

  1. Verify if the dish size is indeed
    adequate for your area and targeted satellite.
  2. Obtain Look Angles readings for
    your city and targeted satellite. This includes: - the Azimuth reading which
    the number of degree is clockwise away from the north. (Use of compass) the
    Elevation reading which is the vertical angle up from the horizon.

B. List of

Installation Steps

  1. Assemble dish with instruction supplied during time of purchase.
  2. With the aid of a compass, orient toward the general azimuth direction and the elevation of the satellite and locate an ideal area to position the dish. Here, there must be no obstructions between the satellite and the dish from trees and buildings. Avoid installation on the roof if at all possible to prevent high wind damage or for ease of access if required. (e.g. side of the house, 4X4 post)
  3. Put in place the dish pole on firm support and keep it vertically plumb to enable accurate azimuth and
    elevation settings.( use 2 of the 4 or 6 lag screws for now ) Feed the RG6 cable through the pole, then mount the dish onto the pole but do not tighten the screws too much for now. Connect the LNB head to the wire that was fed through the support pole and secure the LNB head with the provided screw onto to the support pole.
  4. Complete connections of wiring to the receiver and TV.
  5. As an option you can use a satellite finder by attaching it between the dish and the receiver (highly recommended e.g. SF-95.)
  6. Adjust the elevation to the desired vertical angle; do not tighten the screws too tight to allow for some adjustment...
  7. Now rotate the dish to point more closely to the targeted azimuth position in very small incremental angle, allows 5-10 seconds between any movements of the dish. This allows the receiver to complete a signal scan. A lock response on the receiver would indicate that you have located the signal.
  8. You are targeting signal strength of  between 50 to 80. If you have strong signal strength but no signal quality or lock. Try adjusting the dish a bit to the right or left. Optimum signal quality is between 70 and 100.
  9. Set the LNBF polarization tilt by rotating clockwise for western region (negative LNB polarization) to improve signal quality reading. Rotate counter-clockwise if you are from the eastern region (positive LNB polarization).
  10. Secure the dish pole with the rest of the lag screws.

 

Dish Installation

Determining the Elevation and Azimuth:
 
Compass:
Rotate the Compass until the painted tip of its
needle is on the  Zero
or (N) mark on compass face for proper
orientation. The EAST will be at
the 90 degrees, the SOUTH will be at 180 degrees
and the WEST at 270
Degrees.
 
Azimuth (Magnetic):

Move the dish Left and Right until the LNB arm
is pointing to the
magnetic azimuth value for your location.
 
Elevation:
Move the Dish up and down and set the elevation
indicator on the value
of the elevation value for your location.
 
Elevation Indicator:

Be sure to locate the Elevation indicator ( or
equivalent , depending on
your dish) . Use this indicator to set the
correct elevation of your
location.
 

The satellites are "parked" approximately 22,300 miles above the equator. In reality, the satellites travel from west to east, but to us on Earth they appear stationary because they match the exact speed of the Earth's rotation. (This is a geostationary orbit.) If you stand up now, turn towards the southern hemisphere,and tilt your head up to the heavens, you'll be looking in the general direction of our satellite To find out the azimuth and elevation angle for your location: (City and State), please go this link : Satellite Locator and follow the instructions to to calculate the elevation and the magnetic azimuth of your city.

For a quick estimate of the Azimuth and Elevation of your State, you may refer to the tables in the Telstar5 (T5) Satellite Aiming Angels for the USA.

Now that you have your azimuth and elevation coordinates, what do you do with them?
 

First, survey the site to ensure an unobstructed view in the direction of the satellite. To receive broadcast signals, your satellite dish needs to be positioned correctly. Mount your satellite dish so that the base fits flush with the mounting surface (level if mounted on a flat beam or roof, or on an angle to match the pitch of your roof line). When you have securely mounted your satellite dish, adjust your dish so that the dish mast is plumb, that is, exactly perpendicular to level - this is best achieved using a carpenter's level. With your dish now mounted and properly set, you are now ready to aim your dish toward the satellites.

To set the dish to point up to the satellites, you'll first need to set the elevation. Then you'll point the dish in the proper left-to-right position, to set the azimuth. You'll need to refer to the installation manual for your system for detailed instructions, but here's the short course.

Setting the Elevation (UP), (DOWN):

You can set the proper elevation after the dish is securely mounted. First, loosen the nuts securing the two elevation bolts so that the dish easily moves up and down. Line up the elevation indicator with the tick mark corresponding to your elevation number. Then tighten the bolts. You may need to readjust the elevation up or down slightly to get the best signal. See figure on top.

Setting the Azimuth (LEFT), (RIGHT):

Loosen the azimuth nuts on the LNB arm enough that the dish can be turned smoothly with little pressure. Set the azimuth by moving the dish left and right. Point the dish in the general direction of the satellite, in the southern hemisphere. By using a compass you can better pinpoint the direction with your azimuth number to correspond with the degrees on your compass. See figure on top.

Setting the LNBF Polarization Tilt (Skew):


 The LNBF and/or its bracket (s) are marked in degrees to indicate the polarization tilt or the (SKEW). The proper skew varies with location but within plus or minus 30 degrees in the USA except for Hawaii where the skew is minus 65 degrees.
 
The 30 degrees equals 5 Minutes on the minutes scale of a regular clock. The 30 degrees also equals One Hour on the hours scale of a regular clock. The feed cable at the bottom of the LNBF is usually used to indicate the 6 O'clock mark when it is vertical.
 
Generally the skew is zero if you are in Huston, Texas. At the West States like California  the skew could be as minus 30 degrees ( Clockwise rotation which equals to 7 O'Oclock of the feed cable when looking toward the Dish). In Maine the skew could be up to plus 30 degrees (Counter Clockwise rotation or 5 O'clock if looking to the Dish). Looking at the Satellite(reversing the looking direction) the skew for California will be 5 O'clock and for Maine it will be 7 O'clock.

During the final tune up phase, the LNBF should be rotated in both directions to optimize the signals and/or the quality levels.


Acquiring the Signal:
 

Depending on your kind of digital receiver you will be able to see either the received signal level only or to see both the signal strength and the quality meter also. Please go to this link for details : Acquiring the signal from the T5 Satellite.

Now your dish will be in position to lock in on the satellite signal. You will need to 

1) have your digital receiver connected to your television, with both turned on, and 

2) have your antenna LNB to receiver cables connected, and 

3) be viewing your Setup Antenna/Signal Strength display from your digital receiver's on-screen menu to measure the signal strength accurately.  To view the signal strength and quality (Satcruiser receivers Telstar 5 for example) press Menu, Installation, TP Configuration, select Telstar 5 and frequency 12152 or frequency 11898. For the Starcrusier Receivers Please go to this link for details: Acquiring the signal from the T5 Satellite.

Ask a helper to watch the Signal Strength screen for indications you are receiving the signal, the upper meter is the signal strength, the lower meter is the signal quality. Please note that you will receive the signal ONLY when there is a signal on the lower meter (signal quality). Stand behind the dish, and holding its outer edges, slowly turn it a little to the right to adjust the azimuth. Pause a few seconds, giving the receiver enough time to lock in on the satellite signal. Continue turning the dish in this way until you have acquired the signal or until you have rotated the dish approximately 15 degrees from the starting point.

If you haven't detected a signal yet, return to the starting point and move the dish to the left again. If you don't acquire the signal after rotating the dish approximately 15 degrees to either side of the calculated azimuth angle, loosen the elevation bolts and tilt the dish upward so the elevation indicator moves halfway from the current tick mark to the next mark. Then tighten the elevation bolts.

If necessary, continue changing the elevation in half-tick-mark increments until you receive the signal. After tilting the dish upwards three tick marks beyond the original tick mark, return it to the original tick mark and then tilt it down a half tick mark. Keep repeating this until you receive the signal.

Polarity can play an important role in whether you are able to receive the digital signal at all. Digital signals are not as forgiving as analog signals, it is either you receive it or you do not. For the SatCruiser Receiver only , If the signal meter shows a high signal (over 85% ), and you are still unable to receive the digital signal, then adjusting the SKEW will almost always help. For the Starcruiser Receiver adjusting the SKEW will maximize the signal level.

If the Signal still eludes you, check:

Check to make sure that the mount is 100% level. The portion that the dish mounts on must be
straight up to the sky level. Otherwise you will not be able to find the signal

That nothing--a tree, for example--obstructs the signal that the cables are connected properly to the receiver.

That you have the correct azimuth and elevation coordinates

Fine Tuning:

Now that you have received the satellite signal, it is important to fine tune the dish pointing to make
sure you have the maximum possible signal strength. Maximizing the signal is important, in that, it reduces "rain fade" during inclement weather. Loosen the elevation bolts, then gently continue turning the dish a little in the same direction you were turning it when you began to receive the satellite signal. Pause for a few seconds each time after moving the dish. Turn the dish in this way until the signal quality strength reaches its highest reading and then begins to fall. Then slowly turn the dish the opposite way until you again receive the highest reading on the Signal Strength screen. Important: The Signal Strength reading does not need to be "100." Lock in on the highest possible signal. Tighten the azimuth bolts.

Loosen the elevation bolts. Slowly tilt the dish up and down to improve the Signal Strength reading. When you are satisfied that you have the strongest signal,tighten the elevation bolts.

Free to air satellite installation guide

- Ku Satellite Installation -

Installing your own free to air satellite system can be accomplished by most people that have the patience to follow instructions and a moderate electronic knowledge. If this is not for you, it will be far easier for you to contact a local satellite installer in your area to assist you. This tutorial assumes you wish to receive multiple satellites using a dish mover or rotor. If you only wish to receive a single satellite, your task is much easier as you have but one satellite to locate and your dish will be fixed on the single location. For most broadcasts in the United States and Southern Canada, a dish size of 90cm - 1.2 Meters (35" - 48") is sufficient. Larger dish sizes may be required for more northern or out of footprint locations.
