Why are my Fox stations the only ones that consistently break up or go to static displays?

We frequently experience video breakup/pixilation/freeze-up and audio interruption of the local and national Fox networks.  The problem does not occur on other networks/channels.   Why is only one network or channel susceptible to  interference when all others are strong and uninterrupted?

Channels come in different frequencies. Fox is on a lower frequency, susceptible to interference, low signal levels etc. Check that your cable is tight and in good repair, remove any unnecessary splitters and possibly have a tech out to troubleshoot further

Channels are bundled together, typically 10-12 HD channels will share one frequency due to Comcast's over-compression. It just may be that those channels are all on the same frequency that is suffering from noise, low signal level, or other interference.
