Systems and methods are disclosed to intelligently employ antenna resources in a manner that may reduce interference between communications signals even in instances where multiple separate frequency band communications need to be supported in a vehicle of limited size. A manifold antenna system is proposed that provides a scheme and a physical construct whereby multiple individual radio receiver/transmitter units may share a limited number of transmitting and receiving antennas. The disclosed manifold antenna system is particularly adaptable to aircraft, spacecraft, vessel or vehicle applications where there is limited room for mounting a number of individual antennas as may be needed to support each radio receiver/transmitter unit in an effort to minimize an amount of interference as is conventionally caused by having transmitting antennas located in too close a proximity to receiving antennas.

Method and system for manifold antennas for multiband radios

A system and method are provided for converting radio communication signals between a Digital Fixed Station Interface (DFSI) Internet Protocol (IP) APCO P25 standard communications format and binary serial data protocol standard communications. Received serial binary data may be evaluated, separated into control information and data payloads, and converted to DFSI IP standard data. Incoming and outgoing data communications are processed by implementing decisions about how to handle the information contained in, or to be contained in, the incoming and outgoing data communications based upon the substance, or overarching format, of the data contained in individual data packets, or serial bit streams. In embodiments, decisions and determinations regarding the information include determining that the information is damaged or corrupted and therefore not available to be converted. The data may be discarded based on such a determination.
