Option 3 - Connecting Three or More IRDs
(North American and Latin 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 RF1 and RF2 plugs
on the base of the TracVision antenna. Figure 2-13 shows a typical
wiring arrangement for three or four IRDs. Mount the
multiswitch unit in accordance with the manufacturer’s
instruction sheet.
1. Connect the RF cable labeled "RF1" to the
multiswitch input labeled "LNB RHCP +13V.”
2. Connect the RF cable labeled “RF2” to the
multiswitch input labeled "LNB LHCP +18V.”
3. Connect the multiswitch outputs to individual IRD
inputs. Use RG-11 cable 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).

The use of an active multiswitch will
interfere with the 22 KHz tone sent
by DIRECTV DSS Plus
™ IRDs to
the antenna. As a result, the
antenna will not receive the signal
to change satellites when you
change channels using your
DIRECTV DSS Plus remote.
