PARTS LIST
The package includes an antenna, and a matching network (1).
PLACEMENT
Choose a spot in the center of the ground plane. The antenna should be mounted, as near the center as
possible, however, a clear location is also required. Before drilling any holes verify the area under the
ground plane is clear of obstructions that would interfere with mounting the hardware for the antenna.
MOUNTING
1. Use the antenna to mark six (6) screw holes and one (1) connector hole on the vehicle.
2.
Punch or drill connector hole 3/4” minimum diameter.
3.
Drill six (6) mounting holes (3/8 diameter drill) to accept #14 X 1” sheet metal screws.
Note:
You may also use footprint template (Included on following page), to pre-drill holes.
4. Mount the antenna.
Note:
The front footprint, on left side of diagram, should be attached first to protect the tuning
assembly.
5. Route the coaxial cable appropriately.
Note: actual sealer used depends on environment. Dow Corning Silastic 732 RTV or equivalent is
recommended (not supplied with antenna).
6. Attach matching network to antenna base and connect the feedline to the network female connector.
