The N25-2 is a dual connector version which incorporates a hybrid. This 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 N25-2 antenna port is identical, so that no coupler drop-out problem during automatic landing occurs.
All N25 Series antennas provide complete lightning protection for the associated receivers. They are suitable for mounting either externally, or within a nose radome. The inherent 180° pattern beam may be modified slightly by the geometry surrounding the installation. The N25 antennas are recommended for installations in close proximity to radar dish installations since the antenna’s (glide slope) sensitivity is relatively unaffected by dish motion.
