DM N25 Center-Fed Loop Antenna | 329–335.3 MHz, Dual output, C
The DM N25 Series of glide slope antennas employ a grounded, center-fed loop as the radiating element. The resulting radiation patterns are symmetrical. All DM 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 DM 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.
DM N25 Glide Slope Antenna | 329–335.3MHz, TNCf Connector
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.
DM N27 Marker Beacon Antenna | 74.75–75.25MHz, BNC
The N27 series marker beacon antennas are rugged, lightweight antennas for the reception of 75 MHz marker beacon signals.
These low-drag antennas are designed for simple external mounting and require no cutting of airframe structural members. The largest hole required in the skin is for the connector. Moisture proofing is assured by the dielectric foam filled, white polyester-fiberglass radomes. These skydrol resistant housings are fitted with metal leading edges for erosion protection. The DM N27 antennas are designed to meet the performance specifications of antennas AT-134 and AT-536.
DM N27 Marker Beacon Antenna | 74.75–75.25MHz, C Connector, 6-hole Mount
The DM N27 marker beacon antenna features a rugged and lightweight design for receiving 75 MHz marker beacon signals. The DM N27 antenna has a low-drag design that is simple to install. Mounting to the aircraft does not require a any cutting of airframe structural members. Its dielectric foam filled, polyester-fiberglass radome offers resistance excellence resistance to moisture and Skydrol while the metal leading edges offer erosion protection.
