TracVision 6 Technical Manual
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 6 systems used in
Europe.
Single Multiswitch Installation
(North American and Latin
American systems only)
The use of an active multiswitch will
interfere with the 22 KHz tone sent
™
by DIRECTV DSS Plus
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. You
will need to use the optional
TV/SAT Switch* or a PC to switch
between satellites.
* To order a TV/SAT Switch (KVH Part
Number 01-0245), please call
+1 401 847-3327.

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 connectors labeled
"RF1" and "RF2" on the base of the TracVision antenna.
Figure 2-9 shows a typical wiring arrangement for three or four
IRDs. Mount the multiswitch unit in accordance with the
manufacturer's instruction sheet.

IRDs to
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-6 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).
