Hi all. Your headache is back...
A receiving system with C band and Ku band on the same horn scenario, single coaxial, no extra control wiring....
12 V selecting vertical polarization; 18 V selecting horizontal polarization for both bands.
0 Hz selecting the C LNB; 22KHz selecting the Ku LNB
There is no diseqc implemented control at all, none of the LNBs are meant to react to it.
But: the Ku LNB has two bands: Low (10.7 to 11.7 GHz) enabled on 0 Hz; High (11.7 to 12.7 GHz) enabled on 22KHz.
Now the question:
If the receiver sends 22KHz; will the Ku be tuned to low or to high band ?
In other words, will the 22KHz pass trough the LNB selector and continue to the Ku LNB and pick high band or will not pass trough the selector and the Ku LNB will pick low band ?
Specifications tell the DC (and RF) passes fine on those selectors, but found no data on passing 22KHz. Do you know how they behave ?
