This calculator uses a "K" multiplying factor value of .975 to adjust for the
effect of antenna wire diameter on length which is applied to the free-space
half-wavelength equation. This works very well with #18 to #12 wire sizes.
Enter the Frequency in MHz.
An antenna for 0 MHz will be approximately:
DIPOLE = 0 Foot inf Inches in overall length and 0 Foot 0.0 Inches for one side.
INVERT VEE = 0 Foot inf Inches in overall length and 0 Foot 0.0 Inches for one side.
Remember to cut your antenna wire longer than shown here and then adjust the
length to the desired frequency. Resonant frequency of an antenna depends on
the height above ground and the conductivity of the ground beneath the antenna.
The Inverted Vee is slightly shorter that a horizontal Dipole.
