Log.-periodic “5/8” Helical Mobile Antenna for the 27 MHz CB-Band

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.

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.

2. Installation Steps

Do not use sealer on rubber gasket or other places.

The whip is compatible with all below mounts

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.
