Question

In which of the following type of measurement prior gain knowledge of antennas used in measurements is not necessary?

(a) Absolute gain

(b) Gain transfer method

(c) Gain compromise method

(d) Both gain transfer and absolute gain method

The question was posed to me in class test.

I'd like to ask this question from Measurement of Gain topic in section Modern Antennas & Antenna Measurements of Antennas

Answer 1

The correct option is (a) Absolute gain

The explanation is: In absolute gain method, the prior knowledge of gain of antennas used in the measurements is not necessary. Gain transfer or Gain compromise method requires the standard gains of the antennas used for measurements to compare the AUT.
