| Quote: | Is there a safe way (not shorting out the conductors) of either
detecting or crudely measuring a digital video signal? I've got an
analog signal strength meter, but it won't register anything with a
satellite signal at a jack. How about an LED? Milliamp meter with
diode? A squeeky rat and a couple well placed electrodes? Thanks, Greg

The ideal method is a field-strength meter. Whatever you use would
need to apply the appropriate DC bias to the cable's center conductor
(required to fire up the satellite dish's LNB).
This is not a cheap instrument, and it requires some skill to use
properly. Even used units can run a couple of hundred, and new ones bear
a four-figure price tag.
I have seen what look like relatively inexpensive handheld units
used by sat-TV techs. They appear to be designed to give a quick-and-
dirty "Do I have a signal?" reading. I have no idea how reliable they
are, but I suspect you're still going to end up shelling out at least
$100 or so.
Happy hunting.
