Connecting the IRD(s)
For the TracVision system to work, you must connect the
following cables to your satellite TV receiver(s) (IRDs):
RF Cable
Ground Wire
Connecting the RF Cable(s)
Each RF cable must be an RG-11 (75 ohms) or RG-6 (75 ohms)
cable fitted with F-type connectors. The RF cable(s) should
already be connected to the antenna baseplate (see Step 12 of
Section 2.2., “Mounting the TracVision Antenna” on page 17). The
following sections explain how to connect the RF cable(s) to your
IRD(s).
To connect the TracVision antenna to your IRD(s), choose one of
the following configurations (based on the number of IRDs you
will connect to the antenna):
Option 1 -  Connecting One IRD
Option 2 -  Connecting Two IRDs
Option 3 -  Connecting Three or More IRDs 
(North American systems only)
Option 1 - Connecting One IRD
One end of the RF cable should already be connected to the
connector labeled “RF1” on the base of the TracVision antenna.
Connect the other end of the RF1 cable to the IRD connector
labeled “LNB,” “ANT/SAT,” or “SATELLITE IN.”
Option 2 - Connecting Two IRDs
Two RF cables should already be connected to the connectors
labeled “RF1” and “RF2” on the base of the TracVision antenna.
Connect the other ends of these RF cables to the connector
labeled “LNB,” “ANT/SAT,” or “SATELLITE IN” on the two
IRDs.
The IRD that is connected to the RF1 cable controls which
satellite the antenna is tracking. The IRD connected to RF2 can
select different channels on that satellite but not change the
satellite selection itself.

TracVision G4 Technical Manual
For instructions on RF wiring for
TracNet, please refer to the TracNet
Owner’s Manual
or Technical
Manual
.
Before you connect an RF cable to
an IRD, turn on the IRD and TV
and verify that there is no AC
voltage present on the IRD’s input
connector, measured between
center conductor and shield. If AC
voltage is present on the connector,
DO NOT
connect the RF cable until
you have corrected the problem.
This is a potentially dangerous
condition that will damage the
antenna’s electronics.
