Setting Up the MRX920 Unit
3-8 MRX920/MTX950 User’s Manual
3 Connect the antenna to the MRX920 unit, and hand-tighten the
connector by turning it clockwise until it is secured.
4 Route the antenna wire through the passenger window or
through the door. (See Figure 3.9.)
Figure 3.9 Antenna Cable Through Window
A rear vent window on a mini-van can be another good loca-
tion. Caution must also be taken when opening the door with
a cable running through the window. The cable can be pulled
out of the connector, again adversely affecting performance.
The cable runs
through the window,
which is the preferred
method.
Caution is necessary to ensure there is sufficient room for the cable and that
it does not get crimped.
In some vehicles, there is enough room to run the cable through the doorframe of the
vehicle without crimping the cable. Also, the sound of the internal fan provides
auditory evidence that the power supply is working. Other vehicles do not always have
enough clearance (especially vehicles with rain gutters). Running the cable through a
rear door can be an option. You can also run the cable through a window.
