This option is possible (5+2+4), but you won’t be able to define 1 2-way combiner on the HW Configurator same with 2 TRX will have missing RX & DivRX cabling, but this is fine and this will not generate BTS alarms. You will need also long SMA cables. If you have spare antenna on the Alpha sector, it will also fit on one cabinet. This will be out of standard setup but it will definitely work.
