INSTALLATION
The X- and CX-antenna types can be mounted anywhere on the car,
however, roof top mounting is always recommended.
The oblong X-mount can be mounted 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 X- and CX-mounts are internally equipped with a bendable section,
the antennas can always be adjusted to an upright position independent of
the tilt angle of the installation spot.
The MiniMag (abbreviated: MM) is a small, light-weight magnetic mount with
a high attaching effect. A silicone layer applied to the contact surface
protects the car roof and ensures maximum friction.
Antennas with magnetic mount should be mounted in the middle of the
vehicle roof to ensure best omnidirectional coverage.
Within this antenna series, all whips are compatible with all mounts.
