Calculates the length and bandwidth for a Quarter Wave Antenna

Enter the Operating Frequency to be calculated. Then the output will be the length of a Quarter wave antenna. If you are making a vertical, this would be the length of the vertical radiator. If you are making a dipole type antenna, this would be the length of one side. (equal sides of the center insulator feed point.)
