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 
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 optional TV/SAT 
Switch (KVH part #01-0245).
