Wiki - Repeater Placement Guide

Now that the repeater stickers are available, I think it would be a good place to start documenting the best placement of the stickers on the devices that we have available to us. I will try to keep the same and similar format as the wiki-nfc-phone-performance topic. You can use the Xfd or Diagnostic Card to find the best placement. For those that do not have access to these tools this can be a refference point.

This resource is a good starting point on figuring where to zero in your repeater

When using the diagnostic card or circular field detectors to find the best placement, are you simply looking for where the fiend field is strongest (e.g. the LED is brightest)?

Or are you using the repeater and the detector at the same time to find a place where the detector lights up with the repeater, but wouldn’t without it?

Or something else entirely?

I’m using my circular field detectors to find where the signal is strongest, marking the location and putting a repeater in that location.

I’m the case of the pm3x, I now no longer have to awkwardly angle my hands to get a read. It is perfect.
