I've got five scanners setup under different agencies as I work for two counties and EMS/Fire/Police throughout each . This has been the easiest way to monitor, however I'd like to set them up with external antennas outside my window. Is there a way to use a splitter to have 4-5 all go to one antenna or what would be the best option for this? I'm not familiar with the hardware needed for this, as I've only seen splitters that lets me run two into one antenna. Thanks for your time!
