The curves in Fig. 19.1 represent the impedance along a centre-fed antenna when supplied at a frequency of
The answer is :- 3 The total length is 20.2 m, corresponding to half wave at a frequency of 7.05 MHz. There are three impedance curves. The antenna is therefore being supplied with a frequency of 3 x 7.05 = 21.15 MHz.
