[Lowfer] Antenna Capacitance Question

[cvest at cox.net]

I was curious as to what capacitance would be an "average" number to see on a LowFER antenna . I am building a second
antenna and could use some guidance .

I also have a friend working on a test meter project for determining antenna characteristics specifically designed for LF , so he 
also needs the numbers to decide where to try and "center it up" for use on the LowFER band .

Any and all numbers would be greatly appreciated .
