TCU firmware downgrade

Good point, I think it depends on the characteristic of the resistor you’re using when it is working at RF frequency (up to 3GHz), if you’re using a small (0402 or 0603) SMT 10K resistor, I’m pretty sure it will not impact antenna at all because the resistor will behave consistently as as a pure resistor, meaning no inductance or capacitance characteristic at RF frequency, and given the RF impedance of antenna and cable is 50 ohm typically, the impact of a 10K pure resistor should be negligible. …
