Universal lnbs use 22KHz tone to switch between the l.o. frequencies, and this is why they should not be used with 22KHz tone switches unless you only want to use one l.o. frequency such as 10600.
Switches and other items placed between the receiver and motor can cause communication problems between the receiver and motor.
A diseqc switch placed after the motor or dish controller will work fine with either diseqc 1.2 commands or USALS.
So yeas. Switches are mounted outside, after the ku motor in most systems.
