Enhanced DIRECTV 21-Tuner SWM LNB for Slimline Dishes (3D2LNB) Review

Worked the first time. We had bad ground on the old one at 160 feet. This is now attached with 3 ground wires. The reason for the failure of the old one was a strong thunderstorm. Surge protection and a primary ground line saved the rest of the equipment. We also have a replacement. Without a television, it is really very bad if a woman wants to watch her programs.

I used to replace the LNB SL3S4NR5-01 that looks a bit different. Worked great. I suddenly lost a couple of my DirecTV channels and got error code 771. All my coax connections looked good, there were no obstructions or bad weather. The next likely culprit was the LNB. It looks like many LNB SWMs are interchangeable, so I ordered this one. It installed without tools and solved my reception problem immediately.

I had a 3D1LNBR0-01 13 tuner that worked but on some channels the signal strength was so weak I missed some if not all of the recorded shows. Using the built in signal meter I fine tuned my dish and these are the signals. (They only care about 99 and 103 (ca and cb). Old LNB vs New - 99(ca) 83-87, 99(cb) 91-94, 103(ca) 88-91, 103(cb) 93 -94 Small increase, but I'm most happy about the 99(ca) hit, which caused me problems with the satellite!
