Good evening from Mullion Cove Cornwall.
Having constructed a motor drive to rotate the polarizing plate in my C band LNB, I am now not certain of its use apart from peaking the signal.
On a C band LNB there are two slots, if I insert the plate so that right hand polarisation signals are converted to vertical, will it then automatically convert left hand signals to horizontal ?
Or is it necessary to take the plate out and put it back in the other slots ?
I should have thought about this more before making the motor drive up : )
No amount of searching online appears to spell out the answer to this question for me.
Perhaps because I am the only one who does not realise the answer : )
The motor arrived from China quite quickly and works fine, it should perhaps be obvious having used it as to the answer to my question, but it is not.
I find that a station that had been saved as both V & H where I had previously been trying blind scans with the plate in both fixed positions, requires me to drive the motor driven plate to both positions.
This I think is because it has been scanned and saved that way.
It has been very interesting constructing the drive, even if not to much purpose : )
