I am building my listening post and need help with the setup. I plan to use a splitter to feed 3 scanners. I've seen somewhere a link for a seller, where the cable used to connect from the splitter to the scanners, is one of relative short length. Does someone here knows where I can get these cable(s) from? They are already prepared with the right connectors. I will need one that has on one end an SMA conector, as all the scanners I have are Uniden; HP1, 436 and 536. Help appreciated, thanks!
