Something is up with your setup. Check that the active antenna you are using meets the F9Ps relatively high gain requirements for the LNA amplifier.

Actual impact on accuracy for outdoor short baseline rtk should be close to non existent.

I agree, we have these deployed in the field and have no issues with weather due to using more than the L1 band. Something isn't configured correctly or something failing, such as the antenna.
