- A design change was made to the antenna base and antenna mast starting in October 2005. The radio antenna base size increased from 6 mm

(0.23 in) to 7 mm (0.27 in) for improved stability and radio reception.

- There are two different design antenna masts available. The antenna masts can be distinguished by the outer bottom of the antenna mast. The

first design antenna mast (1) will have a six-sided hex design and a 6 mm (0.23 in) inside diameter thread. The second design antenna mast

(2) will have two flats on the outer mast and a 7 mm (0.27 in) inside diameter thread.

- The second design antenna mast will have more resistance when installing due to the interference fit of the threads in the mast as identified

by the arrows in the graphic.

Note

Before proceeding, verify that the mast and base stud are properly aligned.

- A wrench will be needed to install the antenna mast. When starting to thread the antenna mast onto the base stud, interference will be felt.

The interference is similar to the feeling of a cross threaded fastener.

Important

Use a protective tape or a cloth inside an adjustable wrench when installing the antenna mast. This will help prevent damage to the

painted coating on the antenna mast.

- Tighten the antenna mast.

Tighten

Tighten to 6 Nm (53 lb in).
