The length of a half wave dipole antenna...

The length of a half wave dipole antenna is 0.5 m, Calculate the optimum transmission frequency.

Text Solution

Verified by Experts

The correct Answer is:
300 MHz

`l = lambda/2 = 1/2 (c/v)`
`:. v = c/(2l) = (3 xx 10^8)/( 2 xx 0.5) = 3 xx 10^8Hz = 300MHz`.
