Question

In a parasitic array the elements are shorted if they are connected to a conducting beam.

(a) True

(b) False

This question was addressed to me during an interview.

I want to ask this question from Types of Antenna topic in division Antennas and Wave Propagation of Avionics

Answer 1

Right choice is (b) False

The explanation: The boom does not have to be an insulator. Because there is a voltage null at the center of a one-half wavelength conductor at the resonant frequency, there is no potential difference between the elements and so they can all be connected to a conducting boom with no undesirable effect. In other words, the elements are not “shorted together.”
