I would like to transmit data at 125 kHz frequency. I'm wondering what is the realistical transmission distance that can be achieved with this antenna:
It's a rectangle shaped 9x12cm coil antenna. Transmitter frequency: 125kHz
Inductance: 1.04mH
Resistance: 15ohms
(https://www.electrokit.com/en/product/rfid-antenna-9x12cm-125khz/)
In the description it says 'long-range'. I understand that LF transmissions usually take place in centimeter/millimeter measured distances, so I'm not sure what is meant by 'long-range'.
I'll be using Arduino to drive the antenna for now, and I'm wondering how far I can transmit signal/data and what can be done to increase the LF transmission distance?
I’m looking to transmit at about 1 meter range*
