Increase Antenna Range #502

Closed troglodisme closed 4 years ago

troglodisme commented 4 years ago

I am trying to increase the range of my reader using the library feature PCD_SetAntennaGain

I have followed this comment but can't get any improvement https://github.com/miguelbalboa/rfid/pull/47#issuecomment-285860139

Has somebody else managed to see an improvement in range adding an arduino Sketch change? Could you please share your examples?

Many thanks

The improvement by increasing the antenna gain is not huge. More like 0.5 to 1 cm, which is only useful if the reader is covered by a case. For more range you need a different module (eg. wiegand).
