    how to install a motorised dish

    First of all you are going to need some tools (stating the obvious i know):

    Ladder, remember, working at heights can be dangerous, and you are going to be drilling and carrying equipment up and down a few times, if you dont feel confident then use the services of a professional installer.

    Drill, if using a mains powered drill please use an RCD to avoid any possible accidents.

    Spanners, the most common sizes when working with dishes are 10mm and 13mm.

    Spirit level, to make sure that your mounting bracket is straight, a digital level is best but a bubble level and/or plumb line will manage.

    Drill bits, normally 10mm for plastic plugs and coach bolts but look at your fixings first and a long 10mm bit to drill the wall or window frame to get the dish cable into the house.

    Compass, to help you alaign the dish, a small satellite signal assmeter will also be a great help.

    Sharp knife or wire cutters, to make off the ends of the cables for the connections

    Hammer, to clip the cable to the wall


    once you are sure that your ladders are secure (see pic for a safe angle) and have decided on a suitable location for the dish you can attach the bracket to the wall (ideally this would be south facing). The bracket is normally a square plate with an 'L' shaped pole welded to it but there are many different types available such as tripods. Hold the bracket to the wall and drill your first hole, now you can either attach the bracket by this one fixing and then check the level and drill the other 3 holes or you can hold the bracket in place and once you know its level mark the wall using a pen. either way once you have drilled the 4 holes and attached the bracket you can now mount the dish onto the bracket. (it helps when fixing to the wall that if using an 'L' shaped pole type bracket that it points up, especially if using a large dish, make sure the pole is sealed so it wont collect water)

    It is of utmost importance that this mounting is truly vertical so please be sure to take time mounting it, a few degrees out will mean that the dish will not follow the satellite arc properly and spoil your enjoyment of the system

    You are now ready to start with the dish

    image1

    Assemble the dish and motor as per the instructions.

    Once the motor is assembled you need to set your latitude, on the side of the motor bracket is a scale, and on the motors body is a small mark, alaign the mark with your latitude and tighten them up.

    image2

    If you visit Worldwide map search, route finder and travel directions - powered by Multimap and type in your postal code you will be given your latitude and longitude under the map that it shows you, you will need the figures in brackets (as highlighted in red below) write these down and round them to the nearest tenth. A negative number on the longitude means West, you have to make a note of these for later (so 51.65N becomes 51.7N and -3.64 becomes 3.6W).

    image3


    Now you need to mount the dish onto the motor, this is an important part of the installation as if the dish is not mounted on the motors pole correctly then it will fail to follow the satellite arc correctly and you will not pick up the available signals correctly , The dish has to be pointing away from the center of the motors pole, check this as you are tightening the dish onto the pole because as you tighten the left nut the dish will turn on the pole to the right and vice versa so tighten both sides of the clamp evenly.

    image4

    Fit the LNB to the dish and connect using co-axial cable to the connector on the motor marked LNB. For how to fit the connectors to the cable see how to fit an F connector. 'F' connectors outside MUST be sealed to keep water out, otherwise it will run through the cable, damaging the inside of the LNB and the satellite receiver. Water runs VERY quickly through coaxial cable by "capillary action".

    Using insulation tape or cable ties attach the cable to the LNB arm. And leaving a small loop to allow water to drip off the LNB and cable, connect to the LNB. Now you have to seal the connection.

    image5

    Be sure to use Self Amalgamating Tape to seal the LNB. this is a special tape made of rubber that once stretched will stick to itself and shrink to make a weather proof seal. Cut off about four inches (100mm) and peel off the plastic backing. Wrap the tape around the cable, just below the 'F' connector, stretching it strongly as you wrap in a spiral. Overlap by at least half the width of the tape so it bonds to itself. Continue to stretch and wrap it around the cable then the 'F' connector all the way up to the body of the LNB. Now stretch the excess length and spiral it back down the cable to finish off the joint neatly. once you get back to the bottom of the joint stretch the tape and once it breaks squeeze it into the seal to finish.

    As you stretch the tape to twice its normal length, you create energy that makes the tape melt into itself to form a solid rubber ****. You won't believe this stuff till you try it. There's NO glue. Also great for repairing leaking hose on car or washing machine! The only way to remove it is by cutting with a very sharp blade.

    Now armed with spanners take the dish up the ladder (be very carefull, especially if its a bit windy as they tend to be really good at catching wind when you're not expecting it) and you should be able to hook the clamp on the back of the motor over the wall bracket pole (if its pointing up) tighten the bolts so that the dish is holding in position but can still be turned left and right by turning the whole motor and dish together and the dish can be tilted up and down on the dish itself without using too much force. But dont put the ladders away just yet, you still have to alaign it to all those satellites tens of thousands of miles away

    Assuming that you do not own any sort of satellite alaignment tools (meters) you are now going to need to connect the dish to your reciever and use the on screen signal display to alaign your dish. To do this you will first need to run a cable from the dish site to your reciever, normally under the TV.

    To begin with you need to have a good quality cable, the digital signal will suffer if you cut corners and its only your viewing pleasure that you will be ruining, so it is worth spending that £5 more (approx per 20M) on proper satellite cable than making do with aerial cable. starting from the dish, making sure theres at least enough to reach the motor and a bit of slack, start to clip the cable down to the TV position. Be carefull when using these clips as the nails are quite small and they can fly in all directions, eye protection is advised (but never used). Once you are within a few feet of the TV (but you are on the outside) you will need to drill to allow the cable to pass through the wall to the reciever.

    If you are going to drill through the wall behind the TV then unless you are 101% sure of where you are drilling use a small metal / voltage detector first. its no good having 3500 new channels if you got no electricity to power the reciever cos theres a hole in the ring main cables.

    Using a long 10mm drill bit start to drill the hole behind the TV set, if you angle the drill bit down slightly (about 10 degrees) this will make sure no water can travel along the cable through the wall cavity from outside. once you have drilled through the wall go back outside and finish clipping the cable untill you reach the hole. its always best if the cable enters from below so if you need to put a small loop in the cable its for the best (again to stop water traveling along the cable). Feed the cable through the hole to inside the house and using a **** of sealent seal the hole around the cable. Cable hole tidys are available to make things look a bit better

    image6

    Back inside the house connect your satellite reciever to your TV as per the instructions, this is usually done by a scart lead directly from the back of the reciever straight into the TV set. Turn the reciever on and following the manufacterers instructions locate the motor setup screen using the on screen menu.

    You are now ready to connect the motor and dish, once you have put on the F connectors as shown earlier
    Next we will connect the dish and motor to the reciever and set up the reciever and motor ready for you to start looking for satellites to alaign the dish.

    For menu screen shots i am going to use a Technomate reciever as these are now a very popular choice. The majority of recievers all have very similar setup options.

    First of all connect the lead from the reciever to the motor, now back inside connect it to the satellite input socket on the reciever and turn on the reciever.

    Now before you enter anything into the reciever go back outside and take a quick look at the dish, it should look similar to the picture below, with the dish face itself sitting pretty straight, if not a quick trip up the ladder now will save you pulling your hair out in 20 mins time. Now would also be an ideal time to use your compass to point the dish as due south as you can, it doesnt need to be spot on, but its no good pointing it towards santas house.

    image7

    Back into the house now, and into the motorised setup menu. First of all select a satellite, for this we'll use Thor @ 1'W. Now select your motor type. I always use USALS as its so easy when it comes to adding more satellites. Now you need to enter your latitude and longitude that you wrote down earlier (you did keep them safe i hope). Once all this is done you should have an option to 'Go To' highlight this and press OK. The dish will move slightly. Now if you havent got a signal strength meter you are going to have to rely on the onscreen levels, fortunatley on the technomates these are extremely sensitive and acurate.

    the bars on the screen will more than likley indicate very little or no signal, you need to slowly move the dish to get these as high as possible. On a technomate when a signal is 'locked' the bars will change colour from both red to one yellow and one blue, once they have done this you can tighten the dish slightly ready to fine tune the alaignment.

    First off to start fine tuning the dish hold the face of the dish (the big circle) and only very lightly bend it (it wont damage it) left and right and up and down. This should cause the signal on the screen to improve. Once you have worked out which way to move the dish to improve the signal move it very slightly and again bend the face. Keep doing this untill any way you bend the face causes the signal to drop. You have now alaigned the dish, you just need to tighten it. First of all tighten the elevation bracket on the back of the dish, taking care not to move it.

    Now you need to tighten the motor onto the pole. Be carefull here because if you just go tightening the bolts you will move the dish. As you tighten a clamp onto a round fixing the clamp moves in the opposite direction its being tightened. So, if you tighten the bolt on the left 3 turns, also tighten the bolt on the right 3 turns. Do this untill you are satisfied that it is tight enough.

    You should now have a screen similar to this:

    image8

    Now for the test.

    highlight the satellite at the top of the list and press OK. Now use the up and down buttons to find Astra 2 28.2E and press OK. Now highlight Go TO at the bottom of the screen and again press OK. If asked to save choose yes.

    You will now see this.

    image9

    If you have followed everything then you should have blue and yellow bars to show that the reciever has a signal lock. Now to try the other end of the sky. Highlight the satellite at the top of the list again and press OK, now use up and down to find Hispasat 30.0W and press OK. Back to Go To at the bottom and press OK again, again if asked to save choose yes.

    As long as this locks onto a signal as well then you are all alaigned.

    Now if the 'moving to' box vanishes and you still have no signal dont panic. YET. sometimes the onscreen bar moves faster than the dish, if you still have no yellow and blue bars after 90 seconds then you need to check that you have lined everything up properly (mount vertical, dish pointing from center of motors pole) also check the lat and lon settings on the reciever, i have before now spent an hour at the dish when i had pressed ok on the remote inside and accidently changed N to S which made the dish do the opposite of what it was meant to. If you only get a lock on one side (east or west) DONT PANIC. The usual suspect in most motorised problems is that the dish is slightly off center when tightened onto the motors pole. Check this and go back to the top of this bit and try again, you are so close dont give up.

    Now all the easy bits done its time to find the channels.

    Nahh, congratulations, you have just done what 85% of Sky trained satellite installers could not do, and you have saved yourself the cost of a professional coming in and doing it for you (at least £130), you should be extremely proud of yourself.

    All thats left to do now is either load a ready made channel list onto the reciever (and as you have used USALS any new satellites will be automatically set up) or follow the user manual that came with your reciever for scanning satellites for channels.

    Re: how to install a motorised dish

    Just to clarify those instructions are appliable if Astra 28 East is your central satellite (nearest to south) otherwise you need to adjust your dish on another satellite, it depends by your geographic position.

      Satellite TV DIY

      Satellite television is often installed by a professional technician, but you need neither special training nor prior experience to hook up your satellite dish to receive satellite television in your own home. With only a handheld level, a wrench and some smart planning with a friend, you can set up your satellite dish in short order and with little aggravation.

      Initial Satellite Mounting
      1. Scout out your prospective satellite dish mounting area; choose it carefully. Use a handheld level to measure, and make sure the dish is flush with the mounting surface below it. Look to the sky above to calculate whether any obstructions could impede satellite signal reception to your dish. Such obstacles often include trees or power lines, so relocate your dish if necessary. Also point your dish initially to the general southern sector of the sky. This is a crude aim and need not be precise, but it will save you some adjustments later.

      Satellite Receiver Hookup
      2. Hook up your satellite receiver to your television. It's best to run the coaxial cable that comes out of the back of the dish's mast down to the receiver first to save you a trip. Plug this cable into the back of the receiver via the "ANT IN" port. Connect the satellite receiver to the TV using the included standard A/V cable. To ensure you make the correct connections, take stock of the cable and its related ports. Study the cable and both the back of your TV and the back of the satellite receiver. You will see a set of three prongs on either end of the A/V cable (two sets of prongs total). Each set has one red, yellow and white prong. A corresponding set of A/V ports is on the TV and the receiver, and each is red, white and yellow in color as well. Simply make the connections as necessary.

      Satellite Dish Aiming
      3. Turn on both the receiver and the TV, and select the "Signal Meter Screen" option from the menu that appears. Before returning to the dish outside, consider asking a friend to stay by the signal meter screen, as this will save you time. After returning to the dish outside, use a wrench to loosen both the elevation nuts and the LNB dish arm nuts on the back of the dish's mast. The elevation nuts are directly beside the elevation bolts, and just below these bolts you will also find the LNB dish arm nuts. With these nuts loosened, you may make slight up/down (elevation) and left/right (azimuth) adjustments to the dish to find the satellite signal that beams down from above. Wait for an update from your friend at the signal meter screen, which will inform him as to how close you are to hitting the correct coordinates. Once all the coordinates are hit, you have successfully set up the satellite.

          It depend where do you live.

          London UK is on 0 degrese so central sattelite is the one which is closest to that number so it is Thor 0.8W, I am in Croatia and my town is on abouth 18E so my closest sattelite is Astra 19,2E.

          Iam guessing now bit in Belgium it shuld be on abouth 10E, if I know geography well.

                Re: how to install a motorised dish

                It's better to use an satellite in the real south of your position how discribed, but it works with other satellites too.

                I have set up a motorized dish with an signal of 42 degrees east and there was no problem to reach Astra 2.

                I haven't another choice, because I have only free sight at about 23 degrees my position was at 10 about degrees east.

                If you install your dish properly and take time to set up exactly the best position it works with other positions too, but its more difficult.

                  Other option for motor is to use multiple dishes and muiltiple LNB connected via diseqc avoiding waiting for the motor to rotate
