In which of the following the aperture blocking is reduced by permitting antenna to operate in a single polarization?

In which of the following the aperture blocking is reduced by permitting antenna to operate in a single polarization? Correct Answer Polarization-twist reflector

Aperture blocking is reduced by permitting the antenna to operate with a single polarization in Polarization-twist reflector. Truncated reflector is a type of parabolic reflector. Cassegrain is a dual reflector.

The following items consist of two statements, one labeled as “Assertion (A)” and the other labeled as the “Reason (R)”. You are to examine the two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly. Assertion (A): Polarization preserving fibers have a special core design that maintains the state of polarization. Reason (R): In polarization preserving fibers, there is a stress applying part, which creates slow and fast axes in the core.
