Intermodulation Attenuation (High-Power, 800
MHz)
Intermodulation Attenuation (Mid-Power,
700/800 MHz)
*Full transmitter output power is available during battery revert.
NOTICE: The output power reference plane is the output connector of the power amplifier. The
loss of the transmitter output cable (PA output to back of base radio) is 4% at 800 MHz.
However, the base radio software allows the transmitter output power to be set at 10% above
rated value.
