2: Installation
4. Press the metal plate onto the mounting surface on the vehicle.
5. Apply firm pressure to ensure good adhesion.
6. Place the antenna on top of the metal disc.
Surface Mount
As an alternative to the magnetic mount, the antenna is easily attached
to the surface with four machine screws (no. 8-32). To surface mount the
antenna:
1. Photocopy the bottom of the antenna and use it as a template to
plan the mounting hole locations.
Warning!
Make sure the photocopy is scaled one to one with the
mounting holes on the bottom of the antenna.
2. Mark the mounting hole centers, as necessary, on the mounting
surface.
3. Place the antenna over the marks to ensure that the planned hole
centers agree with the true hole centers, then adjust.
4. Use a center punch on the hole centers in order to guide the drill
bit.
5. Drill the mounting holes with a 3/16-inch bit appropriate for the
surface.
6. Place the antenna over the mounting holes and insert the mounting
screws through the bottom of the mounting surface and into the
antenna.
Warning!
When installing the antenna, hand tighten only. Damage
resulting from overtightening the antenna is not covered by
warranty.
