Been working on an issue with a couple of channels that reside on 72.7, Transponder 18. We have three Smartboxes at a site, with DishPro LNBs, that consistently see CER (codeword error rates) only on this transponder. I have changed out the power inserter, LNB, connectors and cable. The dishes have been peaked as well. The closest transponders with working channels are at Transponders 15 and 23, not experiencing any issues.
I have observed this behavior on the signal meter directly off the LNB, which shows as the SNR fluctuating rapidly and video pixelating. Signal is at -28.6 dBm, with an SNR of 74, 10 feet from the LNB.
I don't have a lot of experience with Dishnetwork or DirecTv equipment or signal.
72.7 TP 18 is 1878 Mghz. PCS cell phone service is the only thing I am finding that would interfere with this frequency. How close does a tower need to be to be a problem? Any thoughts or questions are greatly appreciated.
