I did search but didn't see this exact issue posted.
All my FHD channels disappeared last week. I retuned and got 30 tv channels with poor signal. Not great. Eventually figured out that the cable from the wall to the TV needs held up to carry a good signal. Held it up and retuned. Got 170 tv saorview / freeview channels (Im on the NI border) and all FHD channels showing good signal.
So the cable is faulty or not up to it anymore. Or its allowing interference from something. Maybe 4g.
Whats the best type of cable for this so I dont get any signal interference no matter where it sits behind my tv? Black 1.5m male to male if possible.
