AVR-Chat

Thanks Zack,
After seeing your post I checked Digi-Key.
As far as I can see, they only carry the 'TIRIS' (Texas Instruments RFID) 
stuff.
It is at 132KHz and uses quite large (~1m) antennae.

I am after an antenna <100mm long  (65mm round would be perfect) for use in 
a 125KHz proximity card reader (think of an access control application)

BTW: I am in Sydney Australia.

Thanks for the reply.
Cheers,
Ivan
