Has anyone attempted to connect this to other Proxmark3’s? I ended up ordering the wrong device, I think it’s actually a Proxmark3 Easy. I removed the stock LF antenna, and using low-quality jumpers I wired up the three terminals on the antenna sold here and got these numbers:
Measuring antenna characteristics, please wait.........
# LF antenna: 10.31 V @ 125.00 kHz
# LF antenna: 10.86 V @ 134.00 kHz
# LF optimal: 21.17 V @ 196.72 kHz
# HF antenna: 28.86 V @ 13.56 MHz
Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.
The stock LF antenna gives me:
Measuring antenna characteristics, please wait.........
# LF antenna: 43.04 V @ 125.00 kHz
# LF antenna: 38.36 V @ 134.00 kHz
# LF optimal: 47.57 V @ 127.66 kHz
# HF antenna: 28.86 V @ 13.56 MHz
Displaying LF tuning graph. Divisor 89 is 134khz, 95 is 125khz.
Are the first set of numbers acceptable? I imagine they would improve if I used better quality jumpers, but I just wanted to do a quick test to see if I could use the antenna or not.
