DM N9-9

The DM N9-Series antenna provides a dual band design for both Localizer/VOR and Glide Slope systems for installation within nose radomes on high performance aircraft.

The design incorporates common radiating elements into a single monolithic structure for mounting either on a bulkhead within a radome or to the radome directly. The antenna is designed with the radiating elements attached to a single curved dielectric window to provide support. In some cases, reinforcing ribs provide structural rigidity and mounting adaptability to the bulkhead for mechanical attachment and electrical grounding to the airframe.

The DM N9-Series is a balanced bent-back dipole antenna which renders it immune from the nose radar motion. In addition to excellent Localizer and Glide Slope patterns, many users utilize the Localizer output for forward-looking VOR as well.
