(1)
To meet the FCC 15.247 Part 15 (US) harmonic requirement at full output power, the max allowable antenna gain is 1.9 dBi. Output
power is limited to 9 dBm when using a max antenna gain of 3.3 dBi.
(2)
To meet the ETSI EN 300 328 (Europe) 10 dBm/MHz Power Spectral Density (PSD) requirement, output power is limited to 7 dBm and
6dBm when using a max antenna gain of 1.9 dBi and 3.3 dBi, respectively.
