Signal meter or LNB problem or something else?

    Hi,

    I've had my sat dish up for about a month but have had no luck with getting any channels. It's to connect to a HTPC I've built and which is working fine.

    I've got the dish, LNB and sat cable running into the sat card in the back of the PC. I was previously trying to use a sat signal meter with this set up but it wasn't working (the signal meter wasn't lighting up). So today I got access to a freesat box and hooked that up to the signal meter.

    So, I have a small connecting cable that came with the meter, I connect that to the freesat box and the meter lights up as per the instructions, all well so far. However, I then connect the cable running to the dish and immediately the meter's light either goes dim or goes out entirely and I get no signal.

    I tried two different cables, same result. I tried the signal meter at the end with the dish on it, and at the other end with the freesat box on it. Same result, nothing. Moving the dish around makes no difference, no signal.

    It's not the cable, so could it be the LNB? How do I test for that? Could the signal meter be broken? I'm at a loss as I've no idea what direction to point the dish, I've copied neighbours orientations but still nothing on the signal meter.

    Do these symptoms (meter suddenly dimming / dieing when connected to both wires) sound familiar to anyone? Anyone got any ideas at all as I'm baffled.

    THanks.

    Meter dimming could only mean a short-circuit LNB or LNB connection lead.

    Thanks for the link, I'd actually found that page but only glanced over it when trying to figure out the problem.

    I've subsequently heard from my brother who was helping with the installation, he tried my signal meter on his new sat dish/LNB and he said it worked fine, no dimming.

    It does sounds like an LNB problem, anyone know how to test an LNB?

    Test it with your brother's dish and receiver.
