Wiring 3+ Receivers

A
IMPORTANT!
Only antennas equipped with a circular dual
LNB or a linear quad LNB can support more
than two receivers. Antennas equipped with
a linear dual LNB support only two receivers.
Antenna with Circular Dual LNB
(North American systems only)
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 30).
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).
IMPORTANT!
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 optional TV/SAT
Switch (KVH part #01-0245).
