Yes. At least to a certain extent. The idea is to get from the high-birate I/Q data so something more amenable to transmission over an RS-422 (or -485) serial drop. One example is for an AIS transceiver on a boat. By putting the radio and decoder at the top of the mast, the backhaul can be a cat-3 twisted pair cable, rather than a much heavier coax run from the antenna at the top of the mast to the receiver below decks. Reducing the weight at the top of the mast reduces the moment arm acting on the boat, significantly enhancing the stability of a sailboat (which is how I got started down this road to begin with). --lyndon
