Default Coax To Coax Noise Transfer ?

Hello:

Am about to start stringing some coax from an outside Receive-Only antenna's
Balun up to
my study where the receiver is.

The easiest thing for me is to run it alongside an existing (looks like
coax, but am not sure) wire
that Comcast has strung for my broadband service to the PC. Actually to
their always on modem which is then
connected to the PC.

Was wondering about coax to coax noise transfer into the receiving antennas
coax from being right alongside
this Comcast stuff.

Think there's any reason for concern ?

If so, worth the trouble to find a new route for the receiving antenna's
coax ?

Thanks,
Bob


I know my PC creates a lot of hash that is unkind to a sw radio if
it's within 4 feet or so. I don't know if that hash would show up on
the broadband cable. You might get a portable sw radio and hold it
against the cable, where you plan to bring your antenna feed in. If
you don't hear anything extra, you're probably okay. (You could also
try switching your cable modem on and off to verify any noise your
radio picks up.)
