This LNBF offers a stronger, more stable signal and higher performance. The high gain compensates for longer cable runs. We didn't believe 0.3dB would make a big difference so we tested it - and WE BELIEVE! Plus this is a Quad polarity LNBF with both linear and circular polarity: one dish - more options. Works with FTA MPEG-2 and DIRECTV® or DISH Network™. Plus this strong LNBG helps reduce rain fade and other weather-related problems on DISH and DIRECTV. Test results included with each LNBF. Five year warranty.
