DHX 27 5/8-KFZ - Datasheet

Description

0.9 m high top-quality antenna with high efficiency.
Stainless steel Z-mount with ball-joint and wing screw whip-fastening system.
Despite the very small physical dimensions, the toploading and the log.-periodicdistance between the helical windings yield exceptionally good performance.
Simple mounting with access from the outside only.
Choice between two connection principles:
Z-mount : FME-connection (FME-cable to be ordered separately).
ZP4-mount : Permanently attached 4 m RG 58 cable terminated with FME-connector.

Additional Information

Installation

This antenna is supplied with type Z-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 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.

3.Tuning

The antenna must be tuned using VSWR-meter. Unfasten the union nut at the top end of the whip and pull out the adjusting pin approx. 1 cm at a time until best possible VSWR is obtained. Re-fasten the union nut thoroughly.
