To connect three or more receivers, follow these 
steps to install an active (powered) multiswitch 
between the antenna and the receivers.

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.

(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.
