    have i got an alignment problem?

    Dish is a standard sky mini dish setup for 28.2
    Installed by engineer a few years ago
    Recently been having trouble with a few channels being very blocky and unwatchable
    Channels affected are only on 2 transponders
    And include bt sport hd epsn hd and the other transponder/frequency contain capital tv and heart music channels

    I have a dreambox and a venton and both have issues on the same channels

    I'm not sure if my dish has managed to move slightly over time or anything

    I tried looking at the signal on the venton and dreambox but I don't really know what I'm looking at
    On affected channels I'm getting snr reading of around 39% and 6.8db

    Other unaffected channels show 55% and 16-20db respectively
    Can somebody help me out and point me in the right direction

    Thanks

    Seems slightly out of alignment. If safe to do so, gently push on one edge at a time and see if signal increases.

    You can use apps on your phone such as enigma signal meter/dreamdroid.

    You want to concentrate on quality, not strength.

    Perfectly safe for me to do so as it is above porch roof so no issue there
    Will download the app and see if that can help me

    It just seems a Google search brings up a mind boggling amount of different info

    I think I'll start as you suggested by just nudging it slightly

    If your old sky dish was installed a few years ago it is worth fitting an up to date LNB. They are extremely cheap to obtain from the usual place.

    Do all the alignment checks as well, and you should be sorted.

    I say a few years it maybe 4-5 years
    It's a quad inn but like most things become outdated very quickly
    I'll give it a shoulder barge first see if that helps :-)

    Forgot to say, mark current position just in case you push too much.

    You only need to make a small adjustment.

    A 4 or 5 year old SKY quad LNB should still work perfectly fine if it had the cover pulled down properly over the f-plugs.
    I'd be nudging the dish first as your stronger channels aren't the best either.

    Thanks guys
    Thats my first approach
    I noticed a while ago with bt sport hd and espn hd
    But didn't think much of it at the time until I saw other channels and looked a bit further into signal strength and quality
    Mind I can't say I know an awful lot about it
    I may even have knockined It a bit myself putting some cctv cameras up
