The diameter of the ground plane at the antenna base should be at least three feet for best
performance. Ideally, the ground plane should be a minimum of three times the wavelength
being received. For example, a 900 MHz signal, having a 13 inch wavelength, should have a
ground plane of 39 inches.
Installing the Permanent Antenna Mounting Base
The permanent mount antenna base can be installed on the outside of the roof or trunk of the
vehicle.
1. Drill or cut a ¾-inch diameter hole in the vehicle where the antenna is to be located.
2. Carefully feed the connector and coaxial cable through the hole from the top side and thread
it out of the headliner near the IMR-XA mounting location.
3. Insert the rest of the cable and the lower tabs of the mount body through the hole from the
top.
4. Center the mount body in the hole.
5. Ensure that the rubber O-ring is pressed into the groove in the brass nut and thread the nut
onto the mount body.
6. Finger-tighten the nut and then use a wrench to tighten the nut until the O-ring is com-
pressed. If the mount body spins while you are tightening the nut, use a spanner wrench
applied to the two holes on the top of the mount body to hold it still.
7. Clean the surface of the vehicle around the antenna mount body.
8. Ensure that the gasket is properly set in the antenna base.
9. Thread the antenna base onto the mount body, making sure not to cross-thread the mount.
10. Continue tightening the antenna base until it seats to the vehicle.
11. Complete the cable routing to the IMR-XA in the vehicle and secure the cable.
Installing the Magnetic Antenna Mounting Base
The magnetic mount antenna base can be installed temporarily on the metal roof or trunk of
the vehicle and then removed as desired.
1. Ensure that the gasket is properly set in the antenna base.
2. Pre-assemble the antenna to the magnetic mount by threading the antenna base onto the
mount body, making sure not to cross-thread the mount.
3. Continue tightening the antenna base until it seats to the mount.
4. Before mounting the magnetic base on the vehicle, clean both the magnet surface and the
mounting surface.
