MU 9-XGP4 Mount

Please note that the MU 9-XP4, MU 9-CXP4 and MU 9-XGP4 type “s”-, “l”- and “h” mounts contain matching transformers. Consequently, these special mounts cannot operate with other whip types.

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 ¼ 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.

A polyethylene-covered, closely spirally wound flat steel-band material causes the whip always to stand erect while at the same time being very flexible.

2. Installation steps

2A. (From outside)

Do not use sealer on rubber gasket or other places.

2B. FOR GPS-MODELS (From outside)

Do not use sealer on rubber gasket or other places.

2B. ASSEMBLY INSTRUCTIONS (for GPS-models)

  1. Put GPS-FME-connector-cable through the gasket (2).
  2. Put the gasket (3) + GPS-part (1) over the body (B).
  3. Put the body (B) + gasket (3) + GPS-part (1) through the ø19 mm hole.
  4. Put the housing (4) over the body (B) and be sure that the GPS-part (1) fits into the
    square hole in the body (B).
  5. Put the threaded part over the body (5) and tighten max. 3 ±1 Nm!
  6. Mount the antenna whip.
3. Tuning

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