Requires a marine/VHF antenna with BNC or SMA connection and a PC with USB. Range is limited by line of sight (except during troposphere ducting conditions), the relatively low power of ship transponders and the height and gain of your antenna. Typical range on on the coast with a low level antenna 12Nm, on an elevated antenna position 20-50Nm. 250Nm+ under the right ducting conditions
