[QUOTE="Terryl, post: 1119281, member: 369937"] This is a digital signal your working with, 100% on all channels is not needed anymore, this is not like the old analog satellite days when you needed every bit of signal you could get, I have great pictures and good sound at 40% on some very weak transponders at ether end on my arc. And every thing you add to a system adds signal loss, 3 to 7 dB of signal loss can be almost 1/2 of your RF voltage on the system, cheap coax or coax not rated to 2 to 3 GHz can also add to the system loss. The SNR readings are calculated by the receivers RSSI voltage from the tuner, and all tuners are not the same, you need special equipment to get the true SNR of a system. [/QUOTE]
