AVIONICS

The N25 series of glide slope antenna use a grounded, center-fed loop as the radiating element, which produces the radiation patterns. This antenna is a dual connector that incorporates a hybrid; its circuitry effectively isolates the two associated receiving systems providing protection against disablement of both systems in the event of failure in one system. The radiation pattern associated with each DM N25-2 antenna port is identical, so that no coupler dropout problem occurs during automatic landing. All DM N25 series antennas provide complete lightening protection for the associated receivers. They are suitable for mounting either externally or within a nose radome.
