sheath run a multi-conductor cable, the RF coax lead (within
one sheath), and a braided strap for RF grounding.
Pre-existing holes: Notice some pre-existing holes may be
present in the vehicle body. They are used for ventilation or
for wiring lead-throughs from options that may or may not
be available on your vehicle. Try to utilize these first,
instead of drilling any holes in your car.
Inconspicuous holes: Another idea is to locate a door
“knife-edge” or lip and file a “slot” just wide enough for a
cable to pass through. In many instances the rubber sealing
strip can be reinstalled to cover the cable.
Grounding strap. The importance of the braided RF
grounding strap cannot be over-emphasized—a good electri-
cal and mechanical connection to the vehicle chassis must be
found. (See Chapter 4 for detailed treatment of mobile
grounds.)
The cable is flat and flexible enough to feed through most
door/hatch edges without affecting door closure. Slip a long
sleeve of heat-shrink tubing onto the braid along the length
that will be directly exposed to the air and door sealing sur-
faces (8 to 10 inches should suffice). Try to ground the
braided cable to the chassis using existing bolts and screws,
when possible. Prepare the area where the braided surface
will contact by sanding away the paint and primer until
shiny, bare metal appears.
A part in the braid large enough to pass a screw or bolt can
be made by simply pushing strands apart with a small
pointed object (such as a ball-point pen) to accommodate the
fastener. Remember to re-tighten any bolts or screws firmly
