We have a number of tier trap filters that can block out certain channels within your CATV system. These filters block out full channel segments such as 72 -76 or 62 – 66. Additionally we have filters that can block out channels above a certain number such as channel 60 and above or channel 78 and above. This may be a little bit of an old school technology, but it can definitely help to block out unwanted signals.
All of these filters can be found here when you scroll down the page about half way. http://www.cu1.com/channelvision.html
