The result is for stretched width antennas in free space, medium or minimum 2 x Lambda over ground with sinusoidal current and l>>d. For the resonances frequency and wire diameter have to be specified.
Lenghts are related to free space. The resonance-calculation delivers the lenght for free space. To get the geometric lenght in medium you have to watch lenght in medium. It is beta-software.
For experts I have transfered the 2kl in the auxilliary calculation. For arguments greater than 36 the calculation of Si(x) and Ci(x) is not exact.
