Antenna calculations
###

This will calculate the length of a 1 wavelength loop

This will calculate the length of a half wave dipole.

This will calculate the length of a 5/8 wave vertical with 1/4 wave radials.

This will calculate the length of a delta loop.

This antenna is a triangle shape with L1=top; L2 and L3=sides.

It should be feed with a 4:1 balun.
