It basically depends on the number of LNBs, as well as the number of 7104 line amplifiers in the network.
For the same scalability, the Nevoswitch system provides a better shielding (thanks to its Zamak chassis), the option for each module to be configured either as "terminal" or "cascade" by means of a switch, the ECO mode for low power consumption, and the quality of European manufacturing.
There are many questions relative to whether a splitter or a tap are bidirectional, mostly when a splitter is used as a mixer. Splitter and mixer can indeed be implemented in a single device, since the RF losses are the same for both directions. The only difference resides in current circulation: since the device is equipped with diodes, circulation is directional. The way a tap works is different, and cannot be considered bidirectional as opposed to a splitter. Tap losses (between input and bridging connection) are not equal to through losses (between output and bridging connection). That is why this circumstance has to be taken into account when figuring out the use of signals in the return channel (5 MHz – 30 MHz).
The use of a splitter to replace a tap is not recommended when the different outputs correspond to different users. The reason for this is that the rejection among the outputs of a tap is much higher than the rejection among the outputs of a splitter. Furthermore, any operation performed by a user on its UAP could impact the neighbour sharing that same splitter. Another issue that should be taken into account is the network load. When a tap is installed as the last equipment, a load is inserted on its path so that the whole network is adapted to 75 Ohm. If a splitter is installed instead, the network will not be fully loaded, which will produce impedance mismatches.
He first thing you need to know is the operating current of your power supply unit (e.g. 0,8A for Ref. 732101, or 3A for Ref. 732801). Secondly, the power consumption of your multiswitches and amplifiers. Moreover, generally all of the devices in the NevoSwitch range can be remotely powered at least through the VL entry (vertical low), either top to bottom or bottom to top.
If your system includes an amplifier, you are encouraged to connect the power supply to that amplifier in order to avoid voltage drops and achieve a better performance, since it is the element with the highest power consumption.
Let’s illustrate it with an example: take an 800mA-power supply unit and an LNB with a power consumption of 150mA. The 9-entry NevoSwitch amplifiers (Ref. 714609) have a power consumption of 270mA, the MSW 9x8 (Ref. 714601) of 40mA, and the MSW 9x24 (Ref. 714604) of 130mA (all of them in low gain (LG). Besides, you need to take into account that, should the MSW be used as not cascadable, the loads' switch needs to be activated at the end of the line, which means an increase 45mA on total consumption. This is why the use of this power supply unit allows us to cascade 1 MSW 9x8, 1 amplifier and 1 MSW 9x24 (besides powering both LNB), thus obtaining a total power consumption of 785mA
