    Presumably 75.25MHz is an analogue signal? In the UK, at least while the
    cable system has carried a mixture of analogues and digitals, the
    digitals have been run 10dB below the analogues. If 75.25MHz had been
    digital, it would be set at -5dBmV, so there would be a rising slope of
    4dB, LF to HF.

    In any case, if the 513MHz digital is -1dBmV, and other HF signals are
    similar, that is more than sufficient for a digital set-top box. I would
    think it should work reliably down to around -15dBmV. If I'm right,
    whatever the problem is, it isn't being caused by a lack of signal
    level.

    Because I am not.

    Yes, it is as simple as that. You are within 300ft and the cable company
    must serve you. This is state-of-the-art. Now you'll probably declare
    the whole State of Vermont to be wrong?

    The whole state? Na, there's probably three sane people left.

    But it's everywhere. Here is an example from South Carolina about what
    happens when a company wants to push through a sub-par 125ft and the
    city insists state-of-the-art 300ft:

    They threatened to not renew the franchise. And this was six years ago.

    Geez Michael, one stupid thread and you trash years of positive
    experience?

    Just the same, i didn't expect him to even think of pretending knowledge
    where he was not well versed in the specific area under discussion.
