I purchased the NFC antenna and have a few questions?

1.What is the cable/type called? What is the max length of the cable that attaches the antenna to the x1? I need a cable that is 1.5m - 1.8m. Where would you find such a long cable?

  1. The device(phone) must touch the antenna to initiate a connection?

Thank you

We don’t have antennas that long.

The interface of the antenna is IPEX-1.
It can go through cell phone cases.
How far do you need the detection distance?
