We have an outdoor camera system connected to our cable system. A crucial piece of this is a Channel Vision tier trap filter, which takes out channels 70-79.

Problem is, our reception on the remaining analog channels isn't as good as it should be, and we were hoping to find a filter that didn't take out so many channels.

Any suggestions for these problems? The guy who did the low voltage on our home is angry with our builder and I fear that I'll have to make any changes myself.

Thanks for any help.

You could run a dedicated line for the camera and use the existing line for video and eliminate the trap. Those filters are notorious for making the picture grainy.

The "Q" (quality, or sharpness of the cutoffs) of the filter, is determined by how many stages, or levels, of filtering are used. So, a filter with sharper cutoff points will be larger, and cost more.

You can check out "Channel Deletion Filters" at sites like:
