MOUNTING 18 mm dia. hole
INSTALLATION
The LX-mount is especially suited for roof-mounting. It is recommended to
mount the antenna at the centre of the roof to ensure the best
omnidirectional coverage. Mounting can take place in an 18 mm dia. hole
with access from the outside only.
When cleaning the car in car-washing machines, the whip should be
removed – a 9 mm fork spanner can be used. After wash, the whip is
refitted and tightened lightly with the spanner.
The mount is equipped with a bendable section (±15°) to make it possible
to adjust the antenna to an upright position.
