On the LNB I have, there are no slots. But, is the dielectric plate supposed to 45 degrees to the antennae inside the feedhorn? Does it work if the dielectric plate does not extend all the way to the back? It looks in your pictures that the dielectric plate is 90 degrees to the antennae. Thanks.

Guys, how deep does the dielectrical plate have to be inside the feedhorn? Does it have to touch the back?

Ah ok, so 2-3 credit cards cut so that it fits into the feedhorn. Thanks! I was under the impression that only teflon worked.

Hey guys, What are some common items that can be used as dielectric plates in converting LNBs? Can credit cards be used as substitute for teflon, or cds for that matter? Thanks.

Hey guys, what happens to an invacom when it is at a location where both circular and linear signals are available? Does it receive both signals and output them both?
