- It all Adds Up
Transceiver, and vehicle (chassis) ground. These consist of a
multi-conductor cable together with RF coax lead (within one
sheath), and a braided strap for RF grounding.
As we advised in Chapter 1, you have identified some pre-
existing holes in the vehicle body, holes used for ventilation
or for wiring lead-through from options that may or may not
be installed on your vehicle. Try to utilize these first, prefer-
able to drilling holes in your car. Another idea is to locate a
door “knife-edge” or lip and file a “slot” just wide enough for
a cable to enter. In many instances the rubber sealing strip
can be installed back in place over top of the cable lead-
through.
The importance of the braided RF grounding strap cannot be
over-emphasized—a good electrical and mechanical connec-
tion to the vehicle chassis must be found. The cable is flat
and flexible enough to feed through most door/hatch edges
without affecting door closure. A good idea is to place 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 (8-10 inches should suffice). Try to ground the braided
cable to the chassis using any 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 point-
ed object (such as a ball-point pen) to accommodate the fas-
tener. Remember to re-tighten any bolts or screws firmly.
