Additional Information
Installation (if mounted from the outside)
-
Equip the matching unit with FME antenna cables and the supplied 100 mm junction cable.
-
Draw the 100 mm junction cable through the antenna hole from the outside (e.g. with a drawstring between the car roof and the dome).
-
The Z-mount is particularly well suited for mounting on car-roofs because of its ability to be installed exclusively with access from the outside. The Z-Mount for roof thickness from 2 mm to 7.5 mm must be mounted from the inside. However, the antenna can be installed anywhere on the car, as the Z-mount is equally well suited for mounting on e.g. trunk or wing.
-
Attach the cable to the Z-mount and install the mount from the outside following the below given instructions.
1. Installation Dimension
2. Installation Steps
Do not use sealer on rubber gasket or other places.
3.Tuning
The ML 1-ZR/BOS1 BBMU is factory-tuned to the following 80 MHz BOS area:
LOW: 74.215 – 77.655 MHz
HIGH: 84.015 – 87.455 MHz
Fine-tuning or frequency change can if needed be done as follows:
Adjustment of the BBMU BOS1
- Tune the VSWR in on the desired centre frequency and suitable spacing (for instance 30 MHz).
- Adjust C1 till the VSWR curve emerges on the display.
- Adjust C2 till the best possible VSWR minimum is reached on the required frequency.
- Fine-tune the VSWR minimum and the bandwidth step by step means of C1 and C2.
