Description
The 104-17 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 1.7:1 at 978 MHz when connected with a 50Ω coaxial transmission line. The 104 series antennas feature an omni-directional, vertical-polarize radiation pattern when mounted to the underside of the aircraft.
