Installation

The shadowing effect of the car roof often produces deep nulls in the radiation pattern from short antennas mounted on trunk or wing. This problem is solved using the MU 908-X/…-antenna. Because of the colinear design this antenna provides a satisfactory omnidirectional gain even when mounted on trunk or wing. The X- and CX-mounts can be installed anywhere on the car.

The oblong X-mount is especially suitable for mounting on the often very narrow strip on the rear wing between the trunk lid and the side of the car. Mounting can take place exclusively with access from the outside when drilling an 18 mm dia. hole. Mounting can take place from the inside by drilling a 14 mm dia. hole. When mounting in a 14 mm dia. hole, remove the bottom plastic ring of the packing gasket with a sharp cutter.

When cleaning the car in car-washing machines, remove the whip using a spanner, size 9 mm. After wash, refit the whip and tighten it lightly with the spanner. As the mount is internally equipped with a bendable section, the antenna can always be adjusted to an upright position independent of the tilt angle of the installation spot (up to 30° tilt).
