antena mobila+ antena fixa
recent am gasit pe net aceasta configuratie, intrebarea e daca chiar functioneaza? o foloseste cineva?

As you will know a fixed dish with multiple LNB's (connected to the STB via a switch) will
provide quick zapping to all satellites. However: for practical (and financial) reasons, the
number of LNB's will always be limited.
On the other hand a motorised dish provides an economical way to be able to see many
satellites (only limited by your geographical location and local obstructions).
It is very well possible to combine a fixed dish with a motorised dish, so combining the
advantage of fast zapping to the most used satellites and still have the option to see all
other satellites.
The principle is very simple: a switch can connect several LNB’s to one coax: one of the
LNB’s is the motorised one.
That's really all!
Example:
The fixed dish has LNB's pointing at Astrat1, 2 & 3. These LNB's will be connected to the
inputs 1,2 & 3. And the motorised LNB should be connected to input 4.
Now in the tunerconfig the settings should be as follows:
1- Astra 1 DiSEqC 1.0 port AA
1- Astra 2 DiSEqC 1.0 port AB
1- Astra 3 DiSEqC 1.0 port AC
1- All other satellites: DiSEqC 1.2, USALS extra DiSEqC 1.0 port AD
There is however one point that needs a bit of attention, and that's the wiring.
Normally a motorised LNB is connected as follows:
From the STB (LNB-Input) to the motor (for controlling the motor), from there to the LNB.
The above mentioned combined setup implies that the current for the motor would go
through the switch. Most switches will not be able to survive that (although the specs say
otherwise).
Following this wiring instructions will prevent this: lead the coax from the STB to the
motor, as usual. From the motor go to the switch (output connection). Then connect
switch inputs 1, 2 & 3 to the Astra 1, 2 & 3 LNB's of the fixed dish, and input 4 of the switch
to the motorised LNB.
