Answer 1

A broadside array operating at 100 cm wavelength consist of 4 half-wave dipoles spaced 50 cm apart. Each element carries radio frequency current in the same phase and of magnitude 0.5 A. The radiated power will be

[A].

196 W @

[B]. 73 W

[C]. 36.5 W

[D]. 18.25 W

Answer: Option A

Explanation:

P = n . I2 . Rr, where Rr = 80p2 Ω.

n = 4.
