Although the post looks a bit like a spammed advertisement, I believe that you are searching for help with the development of your product. Unfortunately the attachments with technical details aren't present in your post.

The thread is asking about 125 kHz long range reader "antenna" (inductive coupler), but you still don't tell what's your specific problem related to it. Did you already ask for "125 kHz long range reader" at google.

Either ask a clear question, or the thread will be deleted.
