Cascade Installation
MAW-300 unit has 1 TV signal to RF output encoded as DVB-T Digital TV signal.
Several MAW-300 units can be cascaded in order to increase the capacity. The maximum capacity of a series of N units is 1xN
incorporated TV signals. To cascade 2 or more units, connect the RF output of the preceding unit to the TV input (Ioop-through) of
the next unit (see right iIIustration).
