Only recieving Horizontally polarized Channels

    I have just installed a second dish and to cut a long story short, after troubleshooting for a few hours i only seem to be picking up Horizontally polarized channels, i've checked the channel list on wiki for Astra 28.2e and all the V channels are missing from a scan on the new dish, the signal from the sat is as good as i can get it i think

    14.9 dB
    AGC 97%
    BER 0%
    SNR 92%

    but only on H channels

    The receiver picks up all channels on the old dish.

    Any ideas what the issue could be, the new dish is in pretty good shape , it was never used before , just had it in the garage for a few years, could it be i just dont have it perfectly level?

    It's almost certainly the LNB (it's a common failing in them). Swap it out and full service shall commence :)

    Try the other working box on suspect dish to confirm a dodgy LNB.

    Yes, and the fact you had tried it on both dishes confirms that the issue is at the dish end :)
