UHF-RFID-UNIT-JRD-4035 effective distance
-
Web page shows
"the transmission power of 100mW can reach the effective distance of more than 1.5M."https://shop.m5stack.com/products/uhf-rfid-unit-jrd-4035?variant=39375750824108
But my JRD-4035 effective distance is 0.4M
If possible , could you let me know why JRD-4035 is low performance ?

@PAOPAO Hi there! The required configuration is 920MHZ so the antenna can work the best

@m5stack_ag san,
Thank you for your message!
Could you let me know how to set 920MHZ ?By the way, Specification metal IC Tag of mine is "Up to 4.2M - (US) 902-928MHz, on metal"

@paopao Hi! If using UIFlow, then this is it, if it‘s Arduino. Serial port sending commands
or use API， then CH_index = 1
