LF, VLF,

Onc= e i have=20 created an Excel sheet for calculating my vertical kite antenna on= 137 kHz.=20 Today i want to share it with you. It is in german language but usab= le for=20 everyone anyway i think. It calculates all important parameters of= a vertical=20 antenna and shows the resonance curve.

I am NO expert in writ= ing excel=20 sheets and it can surely be done much more impressive and pretty in= Java or=20 so, but it just works and shows me what happens to the system, if i= change one=20 parameter.

In the yellow fields above, you can type the given= =20 parameters like TX power, antenna height, losses and so. In the lowe= r fields,=20 the needed L for resonance, antenna efficiency, EMRP, ERP, Lambda,= wire=20 voltage and so on is calculated. Additionally you can see the resona= nce curve=20 of the antenna...

If you want you can use or modify it, or th= row it=20 away ;-)

73, Stefan/DK7FC
