LF, VLF,

O= nce i have created an Excel sheet for calculating my vertical kite antenna= on 137 kHz. Today i want to share it with you. It is in german language= but usable for everyone anyway i think. It calculates all important param= eters of a vertical antenna and shows the resonance curve.

I am NO= expert in writing excel sheets and it can surely be done much more impres= sive and pretty in Java or so, but it just works and shows me what happens= to the system, if i change one parameter.

In the yellow fields abo= ve, you can type the given parameters like TX power, antenna height, losse= s and so. In the lower fields, the needed L for resonance, antenna efficie= ncy, EMRP, ERP, Lambda, wire voltage and so on is calculated. Additionally= you can see the resonance curve of the antenna...

If you want you= can use or modify it, or throw it away ;-)

73, Stefan/DK7FC
