I think you don't really know how static mode works.
In Dynamic mode, each receiver has a UB,
Let's say receiver 1 uses UB1 (1210 MHz),
When you zap and select channels on channel list, only one Transponder will appear on that UB 1 frequency. It will be the transponder your receiver asks LNB. Every time you zap, receiver will ask LNB for the (new?) desired Transponder.
But in Static mode, you have to previously program LNB with SAT frequency & Pol. you want to carry on UB1, which one on UB2, UB3......
It's not a mode to work with individual receivers.
It's a mode to work, f.i. when using DVB-S/S2 to DVB-T/C Transmoduladors. and that transmoduladors can't work with unicable dynamic mode.
Let's say you have 4 DVB-S to DVB-C Transmodulators which receive, 11229 Vertical (Astra) , 12699 Vertical, 11053 Hor., and 12383 Hor.
You previously programm LNB to:
11229 Vertical => UB1 (1210 MHz)
12699 Vertical => UB2 (1420 MHz)
11053 Horizon => UB3 (1680 MHz)
12383 Horizon => UB4 (2040 MHz)
and you have to program Transmodulator 1 input frequency to UB1 (1210 MHz.), Transmodulator 2 to UB2, and so on......
You only need one cable and may be a splitter, unless transmodulators have F output connector to feed signal to another one) .
The advantage using Unicable instead of Quad/Quattro LNB, is that in Unicable you have all bands/Pol using only one cable, because each UB is individually configured.
If you did this with QUAD/QUATTRO LNBs, you would need 4 cables from sat dish, because 4 signals are different Band/Pol.
