Can you:

1. point me to a source for the Nordic NFC antenna.

You want a link to where you can buy the NFC antenna standalone?

We dont sell the NFC antennas stand alone, they are bundled with the DK and Thingy's so they should be included in the package. If you did no get one then I would advice you to contact the retailer to see if they can provide one.

[quote user=""] 2. point me to the Specs for that antenna, so I can verify them with the vendor.[/quote]

You can get the files in the download section for the DK, the NFC antenna files are there in the zip that you get there.

Here is the files: devzone.nordicsemi.com/.../PCA64110_2D00_NFC-Antenna-Flexprint-1_5F00_0_5F00_0.zip

There is an old blog here on the tuning aspect of this: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nfc-tag-antenna-tuning , might be outdated.

Here is the documentation related:
