104-12 Monopole Transponder Antenna | 1030 – 1090 MHz MARINE The PS 578 is theThe 104 12 transponder antenna is a mono pole antenna that has a top loaded sphere which creates a factor of reliability and safety for a shorter antenna. This antenna offers a voltage standing wave ratio of 1. 2: 1 at 1,090 MHz and less than 2: 1 at 1,030 MHz when connected with a 50 coaxial transmission line. The 104 series antennas feature an omni directional, vertical polarize radiation pattern when mounted to the underside of the aircraft.
