1.	When a dipole with a parasitic reflector is used as a feed system, the distance between them is _____(a) 0.125λ(b) 0.4λ(c) 1λ(d) 0.625λI had been asked this question by my college director while I was bunking the class.My query is from Feeding Systems topic in section Reflector Antenna of Antennas
Answer» The correct option is (a) 0.125λ Easy EXPLANATION: In a parabolic REFLECTOR antenna, a dipole ALONG a parasitic reflector SERVES well as a feed radiator. The distance between parasitic reflector and the dipole is 0.125λ. The distance between dipole to dipole is APPROXIMATELY 0.4λ.
