Option 3 - Connecting Three or More IRDs (Latin and
North American Systems)
To connect three or four IRDs to the TracVision antenna, you will
need to install an active multiswitch (Channel Master model
6214IFD or equivalent) between the antenna and the IRDs. Two
RF cables should already be connected to the plugs labeled “RF1”
and “RF2” on the base of the TracVision antenna. Figure 2-17
illustrates typical wiring arrangements for three or four IRDs.
Mount the multiswitch unit in accordance with the
manufacturer’s instruction sheet.
1. Connect the RF cable tagged "RF1" to the
multiswitch input labeled "LNB RHCP +13V.”
2. Connect the RF cable tagged “RF2” to the
multiswitch input labeled "LNB LHCP +18V.”
3. Connect the multiswitch outputs to individual IRD
inputs. Use RG-6 cable terminated with F-type
connectors for all RF connections. Terminate all
unused output connectors with 75 ohm DC blocks
(Channel Master #7184, Radio Shack #15-1259 or
equivalent).

Single Multiswitch Installation
(Latin and North American
systems only)
The TracVision system has the
capability to switch from one
satellite to another when you
choose TV channels that are
carried by your two selected
satellites. However, the use of an
active multiswitch may interfere with
the 22 KHz tone sent by DIRECTV
DSS Plus
™
IRDs to the antenna. As
a result, the antenna may not
receive the signal to change
satellites when you change
channels using your DIRECTV DSS
Plus remote.
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.
Due to the signal polarization in
European satellites, the use of a
multiswitch with a dual-output LNB
will result in a loss of signal and
less than optimal operation with
TracVision G6 systems used in
Europe.
