Multiswitch Installation
For multiple IRD/TV installations, an active multiswitch
(Channel Master model 6214IFD or equivalent) is placed
between the Antenna Unit and the IRDs. Figures 2-20 and 2-21
illustrate typical wiring arrangements for multiple IRD and
multiple multiswitches, respectively. Mount the multiswitch
unit in accordance with the manufacturer's instruction sheet.
1. Connect the RF cable tagged "RF2" to the
multiswitch input labeled "LNB LHCP +18V".
2. Connect a second RF cable to the multiswitch
input labeled "LNB RHCP +13V".
3. Connect the multiswitch outputs to individual
IRD inputs. Use RG-6 or RG-11 cable terminated
with F-type connectors for all RF connections.
4. Terminate all unused output connectors with
75 ohm DC blocks (Channel Master #7184,
Radio Shack #15-1259 or equivalent).

RG-6 or RG-11 (75 ohms) cable
or better is required for RF wiring.
Use of non-RG-6 or non-RG-11
(75 ohms) cables will result in
degraded performance and void
the warranty.
