what about L = 468/f MHz?
To calculate the length (in feet) of a quarter-wavelength vertical antenna
Divide 234 by the antenna’s operating frequency (in MHz) [234/f (in MHz)], is that right ?
Also does the thickness of the wire matter?
what about what kind of wire it is does the matter? |

Just remember: Lambda = c/f
c = speed of light = 3 *10^8 m/s
f = frequency of operation
and the length you want should be L=lambda/4=c/4f
Fatter wire is better, but not too important. Any metal will work fine (copper, aluminum, tin foil, whatever). |
