LF, VLF,
Once 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 parameters 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 impressive 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 above, you can type the given parameters like TX
power, antenna height, losses and so. In the lower fields, the needed L
for resonance, antenna efficiency, 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 ;-)
