VOR/LOC/GS TOWEL BAR" TYPE"
The DM N42-1 is a tail-mounted antenna for use with VOR, Localizer and glide slope receivers. It has been specially designed to provide the outstanding electrical performance of a balanced, center-fed loop at minimum cost. The input balun transformer is permanently sealed inside the center housing. Output cables extend from this transformer, through each side bar, to the feed points at the bulge on each element. This unusual configuration permits reliable, economical installation on aircraft that cruise at speeds up to 230 mph. When properly installed, the antenna receives the horizontally polarized VOR and localizer signals with uniform high sensitivity from all directions around the aircraft over the full VOR/Localizer Band. Because of the inherent characteristics of all balanced loop-type antennas, vertically polarized, error-producing signals are rejected. The antenna also has excellent forward reception over the glide slope band (329 to 335 MHz) and can be used for this function by adding a DMH22-1 coupler to the system.
