Monster Cable, especially their RG6!!
I had bad experience with Copper Braided RG6 from Monster Cable. It was at a prewired house so just ran cable from dish to distribution. The guy spend like $400 just on Monster RG6 to rewire his whole house. After I done with my D* install work checking signal strength on xponders and xponder 29 show "0". Known dead xponders in that area are 18,26 and 28 spot beams.
I check the 2nd receiver and no xponder 29 either. Installed my known good test IRD from the truck and that too is not showing 29. Replace the LNB, still no go. I drop the cable from LNB to IRD using no brand name RG6 we use and everything work as they suppose to. Strangest thing ever, only one xponder don't show up.
The problem was there was a kink on the cable before they all goes in to wall.
I took a 20' of that Monster cable to test it at home. If you bend the cable enough to kink it will start dropping signal only on Transponder 29. Where generic RG6, Belden, Comscope etc you can tie like 20 knots in the line and you can still watch TV!
