To connect three or more receivers, follow these
steps to install an active (powered) multiswitch
between the antenna and the receivers.
NOTE: You can purchase an active multiswitch,
Channel Master model 6314IFD, from KVH (order
part #19-0123).
1. Connect the RF1 cable from the antenna to
the “RHCP +13V” jack on the multiswitch
(see Figure 46).
2. Connect the RF2 cable from the antenna to
the “LHCP +18V” jack on the multiswitch.
3. Connect the receivers to the individual
outputs of the multiswitch.
4. Terminate any unused multiswitch outputs
with 75 ohm DC blocks (Channel Master
#7184, Radio Shack #15-1259, or equivalent).
Only antennas equipped with a circular dual
LNB can support more than two receivers.
Antennas equipped with a linear LNB
support only two receivers.

Be sure the multiswitch is properly grounded.
With the multiswitch grounded, you do not
need to ground the individual receivers.
IMPORTANT!
(DIRECTV only) Multiswitches block a
receiver’s 22 KHz tone that the antenna needs
to switch satellites automatically. Therefore,
the customer will need to manually switch
satellites using the buttons on the MCU.
