5. PIFA Antenna (part #: 240.0162):
A. Remove PIFA from plastic bag and uncoil 2ft TNC connector cable.
B. Following step 2, locate a spot along the vehicle underside which will leave a
minimum of 3 inches of clearance from any metal object on all sides of the PIFA
(except the mounting side).
C. Use a minimum of 2 of the 4 integrated mounting holes to bolt the antenna to the
frame or a bracket. Do NOT enlarge the mounting holes in the antenna
body! Use only matching bolts and washers. Do NOT over tighten the
bolts as this may cause damage to the integrated bolt hole sleeves.
D. Mount PIFA with flat side facing the forward driving direction along the centerline
of the vehicle, close to the axles for best results. This will also prevent the
trapping of mud and debris in the base angle of the antenna.
6. Tape up the TNC connectors on both ends of the antenna cable extension to prevent any
dirt or grease from entering the connector during the cable routing process. Ensure that
the proper end is routed from the receiver to the antenna. Run the cable the length of the
vehicle and connect it to the external antenna port on the Wireless Gateway Receiver.
Secure the antenna cable every 2 feet (61 cm) along the chassis with cable ties and
allow for additional cable flex at bend points. Be sure that the cables avoid moving parts
and excessive heat. The following pictures are examples of proper cable routing and
antenna placement.
