Thread: Notch filter reduce signal strength?

I have spent a lot of time and money upgrading my home with quad shield RG-6, DigiMax splitters and Thomas & Betts compression fittings. I also have Insight telephone and watched the tech during installation install the Showtime notch filter in the AT&T telephone box. He showed me the filter prior to installation and I noticed the center conductor of the filter was nothing like the cable I have installed in my house. In fact, it was probably lesser quality than RG-59. Does anyone think that legally removing the filter would improve my signal to noise ratio possibly increasing internet speeds not to mention my analog cable picture quality?

Do you have Showtime or not?

The filter can work either to allow it (likely) or to filter it out (unlikely, otherwise everybody not paying would need the filter).

If the filter is to allow you to see Showtime, then it wouldn't affect your modem signal at all since the filter basically notches out the "scrambling" signal sent within the channel frequency space. It's effective bandwidth is less then a couple megahertz. Removing this sort of filter would keep you from seeing Showtime.

If the filter is to keep you from seeing Showtime, then it totally depends on the bandwidth the filter is designed to "remove".

Either way if your modem is online without a problem, chances are removing the filter won't improve its "speed". It's also very unlikely to improve your analog channels.
