Sky Reception Terrible

    Hi

    I purchased a house in June with a Sky dish on the side of it.

    Rang Sky for a special offer installation and box.

    The guy came out and connected the box - never went near the dish. Appeared to work OK, everyone happy.

    Week later had to ring Sky because a lot of stations were pixelated badly. They said it had to do with the horizontal transponder. I explained the last guy did not check the dish.

    Second guy comes out, replaces LNB and again signal appears to be better. But not all stations are good, just the crappy ones are bad.

    Now all the good stations, both horizontal and vertical transponders are pixelated very badly. Cannot see Sky One, Sports, Smash Hits, etc.

    I can get RTE-TG4 (101-104) fine.

    Sky are sending someone out again to fix this. WHAT should I be looking for from the engineer?

    What SHOULD be done.

    I've asked them to send a height team to put the dish higher but they say this might not be possible. There are small minor branches about 20 yards from the dish.

    ALSO, Am I correct in saying that the signal does not go straight into the LNB from the Sky. It hits a spot on the dish and then goes intot he LNB?

    THANKS!

    The signal comes into land on the whole of your dish at an angle of about 22 degrees. The dish when mounted "straight up" is actually pointing nearly 22 degrees higher up, as it is a mirror to focus the radio waves on LNB. The LNB as you can see is well below the centre of the dish. Imagine the radio waves reflecing down into it.

    Thanks Watty, rang Sky last week and the silly wagon on the other end of the phone tried to tell me that the signal did not bounce off the dish at all and that the signal travelled straight from space into the LNB.

    Any advice on what I can say to the engineer? Are there any boosters/tricks that I shoul ask for?
