M7E Hecto with external antenna - Constant Read

Other
1

I am using a sparkfun redboard iot with a m7e hecto rfid module with an external antenna (UHF RFID Antenna (RP-TNC)). I implemented the “constant read” example and with a power of 22dB and the region North America, I can read up to 40cm, how can I increase this distance up to 4.9ft?

Could be many aspects: the tags, the GEN2 settings, the power-supply, the location (how many other signals are in the same area ? ), the angle etc.

Maybe connect with Simultaneous RFID with motion sensor - #5 by PBrad as they share interesting project with the RFID reader and external antenna.

rfidModule.setRegion(REGION_NORTHAMERICA);
rfidModule.setReadPower(2000);

no obstacles, power supply from redboard 5V, i move the tags https://mou.sr/3DLAjQK in front of antenna.
