  • Mast clamp current probe (MCCP) insertion loss determining methods and systems
    Patent number: 8111205
    Abstract: Methods and systems for determining insertion loss for a mast clamp current probe (MCCP) coupled to a monopole antenna are disclosed. An exemplary method includes determining a first power radiated by the monopole antenna across a first range of frequencies while driving the monopole antenna using a base-feed arrangement to produce a first power-frequency measurement, determining a second power radiated by the monopole antenna across the first range of frequencies while driving the monopole antenna using an MCCP-feed arrangement to produce a second power-frequency measurement and to determine impedance mismatch (MM), and determining insertion loss using the first power-frequency measurement, the second power-frequency measurement and the impedance mismatch.
