Installation
This antenna should be mounted in the car roof to ensure best omnidirectional coverage. 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 antenna can always be adjusted to an upright position independent of the tilt angle of the installation spot (up to 30° tilt).
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 at the centre of the vehicle roof to ensure best omnidirectional coverage.
3.Tuning
The antenna is delivered factory-tuned and requires no further tuning.
Please Note
For safety reasons
1. When using the MU 911-MM/…, car speed must not exceed 140 km/h.
2. If operating the MM-mount with other whips, whip length must never exceed 60 cm, and utilizing this maximum length, car speed must not exceed 115 km/h.
