Still Fighting Intermittent Interference

[Bassplayer 1964]

I have been having this problem for probably close to 5 years now on and off. I ordered the C140 Titanium LNB and have it installed now but I'm still having the trouble as much as before, strangely. Odd thing is it only affects 4180 H on 101 W other carriers are fine, and even stranger when it's really showing up on my Os Mio it plays perfectly on my V8 meter! Some boxes act up worse than others it seems. I have no 5G service here at all yet but there's construction starting straight across from me on the ridge in a few weeks. It will be a Us cellular tower. So my days of TV are numbered because no OTA can be had here There is a tower to the SE side of my dish, maybe 5 miles away that may have 5G on it now and it's US Cellular as well. Any ideas?

What is the OSMio SNR (CNR) reading on 4180 TP when it decodes? What is the SNR (CNR) when it does not decode? Same questions for the V8 meter. One receiver may deal with marginal signal decoding better than another.

My guess is that the SNR is marginal for the FEC and a fix might be as simple as scalar placement (FD ratio) with attenuating adjacent satellite interference or even an adjust skew for an optimized X-Pol isolation.

A spectrum analyzer would provide better data than my guessing. Are you observing any interfering terrestrial carriers within or below 3890 MHz.

To my knowledge, US Cellular does not hold N77 High Band licenses, only N77 Low Band.
