Fox News channel

Mainly happens evenings during prime time. Not so much during the day or late night. Makes no sense to me. Only noticed signal denigration on one channel. 

Thank you for confirming that @user_olacco, we appreciate it. Have you tried restarting your cable box yet? 

Yes. Reset box and installed new hdmi cable. May be nearby 5g cell tower or weak satellite signal to local xfinity. Strange that is only one channel and mainly early evening.
