Antenna impedance matching: F2 unknown

[fgardt]

The part named F2 in schematic and BOM has a value of 0. What would be the correct value here?

(also: since I can‘t find any info on this anywhere, do you know the impedance of the ESP32-C3 itself?)

May be i am wrong, but i think is a 0 ohm resistor.

Is the Wifi range correct without maching pi-network?

F2 is just a bridge (0Ohm resistor), and for the C3T there isn't any matching network and impedance matching done. The C3 includes a PI-network and is properly tuned.
