q
hicle.

WARNING!
Mount the AH-740 securely with the supplied
nuts and bolts. Otherwise, vibrations and shocks due to rough
terrain could loosen the antenna. It could fall, causing per-
sonal injury.
•
For the greatest radiation effectiveness, position the anten-
na as high as possible.
•
For human safety, mount the antenna at the front and oppo-
site side of the driver's position, whenever possible.
- Refer to the pictorial installations and scenarios shown on the
pages 2 and 3.
•
Make sure to allow enough clearance around the antenna
so that any antenna flexing will not damage the vehicle—
bear in mind that the Main Assembly can flex as much as 16
cm (0.63 inches), without damage.
• Make sure the antenna is as far from the vehicle’s vertical
and horizontal metal panels as possible.
•
Mount the antenna on a mounting base with a 17 mm
(0.67 inches) hole for the M16×2 mm (M0.63×0.08 inches)
threaded mounting stud.
•
Rotate the Main Assembly until the ground strap is directed
towards the vehicle body, and then firmly tighten the stud
nut.
•
Use only the original hardware and proper tools.
