As I can see, MiniWhip antenna is widely debated today.

I use Stefan´s VLF E-probe antenna on my Apollo grabber and I am sure, that feeder is not used as the antenna, becouse:

1) I use long symmetrical and shield  cabel

2) Both ends of cable line are ended by symmetrical transformers 

3) The shield is grounded on the both ends

4) I use batery power for my antenna

5) If the antenna is switched off, there is not signal on the screen

6) If the antenna is  detached (there is only feeder+transformers on the input of receiver), no signal is received.

The scheme is on my website.
