Quote from kablegoddd: "A better way would be to digitize the outputs of your RX's at the cabinet, mux them together, and send them back at a sub band frequency other than your current CM frequency. Use a diplex filter to insert them into the RF amp cascade, and high pass the common leg feeding the forward system. At the headend, feed a demux from the Node A return to separate your returns back out. At this point how you combine them into your reverse combining network is up to you. The threshold for noise on the digitized carrier is much lower than the analog CM carrier you are now using."
Kablegoddd, could you explain 'digitize' more? I don't understand, isn't the siginal already digitized?
