Isolation Instructions
The following instructions explain how to isolate the LNB from
ground in a TracVision R4/R5/L3/S3/C3 antenna that has a serial
number earlier than 060900472. You will simply install the four
ground-isolating nylon shoulder washers provided in the kit.
Tools Required
a. Turn off the antenna and unplug all connected
receivers.
b. Using a #2 Phillips screwdriver, remove the eight
#8-32 screws and washers securing the antenna’s
radome to the baseplate (see Figure 1). Carefully
remove the radome and set it aside in a safe place.

nuts and flat washers you removed earlier. Ensure the
shoulder washers prevent the metal hardware from
coming into contact with the reflector bracket.
