Title: Circular polarization feed horn Post by desert on May 2nd, 2011 at 8:42am
Hi,
Can i use Andrew 1.8m antenna with OMT circullar polarization in mode linear polarization ? Can remove circular polarizer and use like linear ? Thanks, |

You can remove the polariser and use the OMT direct to the feed. This make it a linear polarisation system, but be sure the LNB and BUC are properly supported by a bracket. Keep the polariser and the surplus screws etc in a safe place for possible future use.
Alternatively, turn the OMT deg relative to the polariser so that the pins/slots inside the polariser line up with the OMT waveguides. You then have a linear polarisation system, the polariser won't get lost/stolen and the mechanical support arrangements remain good. You can also put it back to circular (pins/slots at 45 deg relative to the waveguides) if needed in the future.
