Subject: CATV Sub Band Use
Reference your post on the RFI reflector.
CATV Systems use the sub bands in various ways. Most often it is used for what
is commonly referred to "as return signals or two way feed." By utilizing
these frequencies, there are at least 7 additional video channels in this range
below the normal Channel 2 assignment. Many cable systems that offer internet
service utilize these frequencies for their outgoing (transmitting out) service.
The cable system still must keep these frequencies confined within their
distribution and trunk coaxial cables to avoid interfering with other principal
users of these frequencies.
Don't be surprised to find that the problem could very well be the internal
drop cable serving your home or another near by as the drop cable is more
likely to leak than the hard-line because of flexing action due to the wind and
similar environmental factors, especially corroded F fittings or improper
splices.
73 and hope this helps you.
