Question

Relation between skip distance d, virtual height d and MUF fMUF is ______

(a) \(d=2h\sqrt{[\frac{f_{MUF}^2}{f_c^2}-1]}\)

(b) \(h=2d\sqrt{[\frac{f_{MUF}^2}{f_c^2}-1]}\)

(c) \(d=2h(\frac{f_{MUF}^2}{f_c^2}-1)\)

(d) \(h=2d(\frac{f_{MUF}^2}{f_c^2}-1)\)

I have been asked this question in homework.

I'd like to ask this question from Virtual Height in section Virtual Height, Critical Frequency and Muf of Antennas

Answer 1

The correct option is (a) \(d=2h\sqrt{[\frac{f_{MUF}^2}{f_c^2}-1]}\)

Easy explanation: Relation between skip distance d, virtual height d and MUF fMUF is given by

skip distance \(d=2h\sqrt{[\frac{f_{MUF}^2}{f_c^2}-1]}\)
