        Not sure what to do. I live in zip 91104 and I am like 5 miles from all the standard network station antennas. I have clear view of all the antennas on the nearby mountain. My house is two story and the antenna is in the attic. The antenna is a GE attic mount 33692. I have great reception on two TVs, but I am getting major pixelation on the living room tv which is fed by a TiVo Roamio OTA box. The pixelation seems to be mostly on NBC. Often it gets so bad that we can’t watch it or hear it. Tried an antenna amp and it was much, much worse. I have quad shield RG6 thru the house except for a 25 foot piece of RG59 run to the antenna. I think my signal may be too strong? I’m not sure if there are any cell towers nearby. One other thing, the plywood sheathing on the roof has a foil coating on the inside.
        Any suggestions will be greatly appreciated- you know the saying “happy wife, happy life” !!
        Thanks

          It sounds like the tuner in your TiVo box is very sensitive or you’re getting some interference. You could try the ANTOP adjustable gain amplifier. This will allow you to adjust the output from the amp to the tuner. You can dial in the right amount of gain. It also has a built-in cell phone filter.

            I considered that the signal was too strong, so I moved the antenna about 90 degrees off and I am still getting like 70 plus signal strength and mostly 100 percent signal quality. I will give it a few days to see if that fixes it.

              Reception issue:
              My OAP neighbours have just got a new smart TV , Antenna and cabling. Antenna guy has been out to them a few times checking testing and rechecking his work confirming all on his end is really good.
              Problem is they are still having pixelation. He has tried many different methods including amplifier disconnecting old cabling to other tv points etc.
              Thoughts are it’s maybe an interference issue from something electrical. I have switched off and pulled out all electrical fuses other than tv one. Glitching still happens. What’s not off is a fridge and an alarm system. But both of these have been switched off previously and glitching still happened.
              Glitching mainly happens from 6pm onwards. – I have noticed that my AM radio loses reception when driving into their driveway directly opposite a street light. The power providers own the light and say they can’t justify spending tax payers money to check the light until all other possible sources eliminated. What else can I do/ is it even possible the light is causing it? What test instruments will help locate the interference?
              Apologies for the long winded post I just wanted to mention what has been tried already. Sparky here btw.

                It sounds like it could be the street light. Here is an article explaining how this can happen. https://www.te.com/usa-en/industries/intelligent-buildings/insights/emi-filters-for-street-lights.html

                You could try using a Ferrite Ring Core or a Noise Suppressor Power EMI Filter. By placing these on your antenna power it could help clean up the issue.
