Advice Needed How are the Dishes in a Dual Offset Antenna Setup Connected ?

[Martin S]

Hi all,

Apologies if I sound clueless, but I have a dual offset antenna setup on the top of the building. I am trying to work out how the larger dish is connected to the smaller dish with the LNB.

Would this typically be via a cable or is the larger dish sending a signal over the air to the smaller dish ?

Thanks in advance !

Hi Martin, welcome to the forum.


Its not a silly question.

The lnbs on the dishes will be connected to what is known as a disecq switch. A single cable then runs from the switch to the the receiver.

Effectively a disecq switch is a combiner unit, and the receiver is set up so satellite 1 is on port A, satellite 2 is on port B etc.

2 and 4 port switches are common, some enthusiasts have 8's and a few folks with extreme systems have 16 or more!
