Default Antenna Length Formula

(Al) wrote:

Once upon a time when I was taught physics, I was told that full wave
lenght should be calculated by dividing the speed of a light
(299820km/s) with the frequency(in MHz)/1000, so for full wave dipole
it should be 299820*160.89/1000=1.864m, for half-wave dipole divide
the result by two.


You need to reduce that number by 5% for typical vertical whip antenna
calculations.
