"Apparently I didn’t need a digital aerial as I first thought it was just a faulty wall plate."

Thank you for a quick response. Martin in Blackheath

"Would highly recommend this company we had a satellite installation to three rooms. The installation was very discreet and the work was carried out in a professional manner."

Would highly recommend. RR Kent


There are two ways of connecting your satellite system up to your video recorder and television set. The most common is by means of those leads which have a TV plug on each end. The other way is to use SCART leads which uses thick cables with 21 pin plugs. While it is technically better to use the SCART, the end product will not worth deal as far as the picture is concerned but will be much better where the sound is required to be of top quality, especially in the case of stereo transmissions. Satellite receiver most handbooks guide connections example using both R.F. and SCART leads, but do not go into detail about Cross Modulation.

Cross Modulation (“Xmod”) can be thought of as a virus that may be difficult to clean up. Basically, Xmod occurs where various signals from TV stations, satellite receivers and video recorders from TV sets get on top of each other, thus de-rated our picture and producing generally strange scenario such as“Herringbone”, “Venetian Blind”, “Wavy Lines” and “Graininess” on the picture. During stormy summer weather, it will cause “Foreign interference” on your TV. So here are some simple guidelines to help you get perfect pictures, on the assumption that the dish is already installed accurately. We shall take care on the R.F. lead method of connection since this is far more likely to produce Xmod than the SCART method.

1) The basic connection layout

2) Remember the chain

First, TV aerial are installed into satellite receiver. Second, RF lead from satellite into video recorder (RF in or TV in). Third, RF lead from video recorder (RF out or TV out) to the aerial socket on the TV set. Basically, you need to remove TV aerial wire from the rear of the video recorder and connect it into the satellite receiver socket marked RF in or TV in. Fit another lead between the now vacant socket on your video recorder and the RF out/TV out socket on the satellite receiver. At this stage you should check that the TV and video recorder are working normally.

3) Tuning in the satellite to your TV.

Select a spare channel on your TV and use the channel number which you already use for the video recorder. Now make sure the TV is switched on and this new “satellite” channel number is selected. You should see a blank screen. At this stage, it is a good idea to practice tuning your TV. Refer to your TV handbook and tune this new channel to get ITV or BBC. Learn how to STORE this channel. Test that it has stored by changing channel then back again . Check does it lost colour? Check the sound to make sure there is no buzz. Now that you have practiced tuning your TV, find out how to tune your video recorder by selecting a spare channel on it as you will want to be able to record the satellite programming.

Change your TV set to the normal video channel so that you can see what is reference to the screen. Tune in Sport or BBC on the spare channel on your video recorder and STORE it. Having mastered the tuning of both your TV set and your video recorder, the satellite receiver is ready to on-line.

4) Receiving Satellite

Configure a test signal from the satellite receiver. This is done by pressing the "services" button on your satellite receiver handset to

generate a menu picture to look for. On the TV set select the new unused channel and tune this until you see the menu picture. Press STORE on the TV handset. Now off the satellite receiver and you should have a totally blank screen. If you have any sign of a picture or wavy images you have the makings of “Xmod” described earlier. Switch on the receiver and change the RF Out channel to a different number, then re-tune the TV channel to view the satellite picture. Repeat this process as many times as needed.

5) Recording Satellite

Simply switch to the video channel on the TV set to bring the video recorder into play for satellite. Return to the video recorder and tune in the spare channel until the satellite picture appears on the TV screen. Remember to STORE it.

Problems that you might face

1 Buzz on sound = re-tune TV satellite channel slightly. Be sure to turn off the Automatic Frequency Control (AFC) while you do it.

2 Black & white picture = re-tune TV satellite channel as above.

3 Records in black & white = re-tune video recorder satellite channel

4 Buzz on sound recording = re-tune video recorder satellite channel

5 Grainy or poor quality pictures = bad RF leads

6 Recorded movie pictures fade in and out or picture rolls.

If you make your own RF leads, use satellite cable and be sure to solder the centre wire inside the hollow pin of the plug. Do it faster by not melting the plastic core of the plug. If you connect your system by using SCART leads instead of RF leads,the picture quality may be better and you will benefit by having high quality stereo sound available, if needed.

Note that, if you want to record a satellite channel that is possible but you can’t watch a different satellite channel at the same time - although you can watch a global TV channel while recording from satellite - in which case you won't need the video recorder anyway. DO USE GOOD QUALITY RF LEADS – NOT CHEAP WHITE ONES FROM THE MARKET – AND KEEP THEM AS SHORT AS POSSIBLE.
