Dual C-Band feed and switches

[Comptech]

Hello, Right now I have a C2 LNBF on my 8 footer and Invacom dual on my 1.2 meter dish running to a 4x4 switch feeding four recievers. I would like to switch to high stability lnb's for the c-band side. Could I use a dual feed with two lnb's and hook them to the 4x4 and still recieve both polarities on both Ku and c?

it should work. you can use a dual c band feedhorn with some norsats or other good lnbs.
connected to the multiswitch.

The problem you get into is that on vertical you are sending 13v up the coax to the vertical lnb. Most lnbs require more voltage than that. an lnbf is designed to run on 13v vertical.
most lnbs need 18-20 vdc all the time because polarity is typically changed by way of a servo motor or it is just a fixed polarity manually skewed in some applications.

You could always use a power inserter on the vertical side between the switch and lnb.
this would correct your volt issue.
I have a dual c and dual ku feedhorn on my 10' dish.
Idon't seen to have any issues running my vertical dms bsc 211 on 13 volts.
it works fine but i have heard that some lnbs have issues.
