This will calculate the length of a 1 wavelength loop.

Frequency in Megahertz	Length of loop

This will calculate the length of a half wave dipole.

Frequency in Megahertz	Length of half wave length wire in feet

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

Frequency in Megahertz	Length of 5/8 wave vertical in feet	Length of 1/4 wave radials in feet

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.

Frequency in Megahertz	Length of L1 in feet;	Length of L2 and L3 in feet
