The whip is compatible with all below mounts

Whips from the Z/ZP4 mounts and the MG-mount are NOT compatible.

Hat screw option:

(Z-/ZP4-type models only): For antenna delivered with hat screw instead of wing screw add a K to the antenna designation.

Installation

The antenna whip comprises a ¼ λ section, a phase shifting coil, and a ½ λ section. 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 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.

The “MG”-mount antennas are provided with a large-diameter, thoroughly magnetized permanent ring magnet with an extraordinarily high attaching effect. A silicone layer applied to the whole contact surface protects the car roof and ensures maximum friction.

Please note that the whips from the Z/ZP4-mounts and the whips from the MG-mount are not compatible.
