Install the correct antenna mast. | DO NOT replace the antenna base. |
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. A wrench will be needed to install the antenna mast.
Important: Use a protective tape or a cloth inside an adjustable wrench when installing the mast. This will help prevent damage to the painted coating on the mast.
Tighten the antenna mast.
