Which HF antenna?

I want to sniff data exchange between my reader and card.

I found several antennas for PM3, both pre-built and DIY.
Which one should I select?

Re: Which HF antenna?

13.56MHz

I'm trying with this antenna:

At first I was not able to achieve a stable eavesdropping.
But I played with antenna configuration a little bit (primary I equalized lenght of turns and fixed all using adhesive tape) - now it seems to work ok.
