Question

What will be the length of half wave dipole antenna at 150 MHz?

• A. 6m
• B. 3m
• C. 1 m
• D. 2m

Answer 1

Answer: (C)

As we know the relation
$1=\frac{\lambda }{2}=\frac{1}{2}\left(\frac{c}{v}\right)$
$1=\frac{3\times 10^8}{2\times 150\times 10^6}$
$=\frac{3\times 10^8}{300\times 10^6}$
$=\frac{3\times 10^8}{3\times 10^8}=1m$
