1) See the below table and note the elevation & bearing for your area.

2) Use a compass to locate your required bearing (Azimuth), try finding a landmark on the horizon so you can put away your compass.

3) Ensure that your Freeview or SKY decoder and TV is switched on.

4a) If you are using a Winegard wind-up satellite dish:

Press the button on the white elevation meter. It will display the elevation and stay illuminated for approx 30 seconds.
Wind up the Dish to the correct elevation level for your area.

Now rotate the dish to the landmark point you've previously found on the horizon. The arrow on the Winegard control panel indicates the direction it is pointing.

If you don't manage to lock onto the satellite straight away, try scanning the sky very slowly through the 10 degrees either side of your landmark. The elevation may have changed as you rotated the dish so double check that it is still correct.

4b) If you are using a portable satellite dish:

Find a suitable place to set up your satellite dish. The arm needs to point towards your landmark (that you have already picked out) so make sure there are no tall trees close by and in the way.

Now adjust the elevation. Most portable dishes don't have an accurate way of determinig this (it's usually a case of trial and error). If the previous town's elevation was 41 deg, make a notch on your elevation mechanism which notes this. If your new town requires elevation of 39 degrees, you will obviously have to lower the elevation slightly.

In the sky, there is a second satellite nearby the one you are trying to find. If you are using a satellite meter, it will 'screech' at you even if you are locked onto the wrong satellite. No picture may mean you are locked on to the wrong satellite.

If you still have no success, try this technique;

Pick up the dish an hold it against your chest (you need to hold it very tenderly, perhaps even give the LNB a little kiss....) Scan the general area listening for the broken parts of sound coming through the TV! This is a good indication you have found the satellite and just require some fine tuning. I find this method works best.
