Installation

This antenna is especially designed for installation on non-conducting surfaces as e.g. glass fibre roofs, as can be found on some trucks, busses, transport vans and trains.

The antenna is an end-fed, ½ λ-dipole concept which can be fed in such a way that the antenna does not require a “ground plane” as required by the standard 1/4 λ, 5/8 λ or collinear mobile whips.

It is useful to note that this antenna type can be used anywhere where the ground plane is poor or completely missing, as e.g.: side-mounted on a clamp as a pager antenna on a wall or mounted at the very edge of a ground plane without the loss induced by a tilted radiation pattern.

The antenna must be mounted on a horizontal surface. When cleaning the vehicle in car-washing machines, the whip is easily dismounted using a spanner, size 9 mm. The whip is refitted again by screwing it onto the M6 thread stud on the mount and tightening it lightly with the spanner.

1. Installation Dimensions

2. Installations Steps (From outside)

Do not use sealer on rubber gasket or other places.

3. Tuning

The antenna should always be tuned using an VSWR-indicating device. The cutting diagrams below serve as a guide for this procedure.
