Additional Information
Installation
This antenna is provided with type BZ-mount. The whip is fastened to the mount by means of our standard ball-joint and wing screw system. The adjustable ball-joint ensures that the whip can always be mounted in a vertical position independent of the angle of the installation spot.
The BZ-mount is particularly well suited for mounting on car-roofs because of its ability to be installed exclusively with access from the outside. The BZ-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 BZ-mount is equally well suited for mounting on e.g. trunk or wing.
1. Installation Dimension
2. Installation Steps
Do not use sealer on rubber gasket or other places.
Please Note
1. As standard the antenna is provided with wing screw. However, the wing screw may be replaced by the less obtrusive hat screw (with key), which also gives an improved protection against theft. To order the antenna with hat screw, please add a “K” to the antenna designation.
2.The antenna can be delivered factory-tuned to customer’s frequencies. Please consult our price list concerning additional charges for adjustment by cutting.
3. Tuning
The antenna should always be tuned using an VSWR-meter. The cutting diagram below serves as a guide for this procedure.
