Unexpected issue was causing Saorview probs

    This may be of help to people who are experiencing Saorview signal problems.

    While doing some software updates I decided to do a bit of a cable tidy up behind the boxes. I assumed wrongly that the software updates were responsible for the now terrible saorview signal, and started on a rampage of software updates!

    It turns out that my signal problems were from where I decided to wrap my coax cables loosely in a loop with cable ties. As soon as I unwrapped the cables i could watch terrestrial again :)

    The loop was only about three turns but it seemed to be enough to make a mess of things.

    Just looping single cables shouldn't cause problems. Had you several cables bundled together? Maybe HDMI cables included?

    Nope, just the coax. The loop was sitting on the rats nest of every other cable.

    I'd be interested to know if you could replicate the problem by looping the cables again, it seems a little unlikely to me as coax is shielded.

    Is it one of those premade (usually white) fly-leads that go from wall socket to TV?

    Rubbish screen on the coax cables.
    But I'd always make each loop separately (They are good as they reduce common mode signals). Then tie the individually tied loops.

    If screen is poor then looping together acts as a transformer.

    There is also a large minimum size of loop, about large saucer sized for decent cable. Though with really "heavy" cables it's large dinner plate size. With Massive coax for masts it can even be 1.2m dia min for a loop!
