xEM Antenna Options

Hi everyone,

I have an xEM implant that I would like to clone an Indala card onto using a proxmark (V2 dev kit from Elechouse). I can successfully clone the card to a T5577 key fob, but the stock antenna doesn’t seem to couple well with the implant.

I’m thinking I need a new antenna for this, and I’ve seen some people mention using the antenna from the xEM access controller, building their own, or others potentially for sale.

What would be the best option?

Thanks.
