I could use this as an interface between PICs and use PICBASIC PRO and use 1-wire or some other protocol?
Anyone have any thoughts?
This was commonly done, before cable/satalite TV, people used to put preamplifiers on the antenna mast, and power it from a wall wart on the ground using only the coax / twin lead cables. Remember chokes pass DC and block AC, Capacitors pass AC and block DC.
