Table 15: Gtr 8000 Base Radio Specifications For Iv&D Uhf R2 (435-524 Mhz) - Motorola ASTRO 25 GTR 8000 Manual

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) 3% at 450 MHz. However,
the base radio software allows the transmitter output power to be set at 10% above rated value.
If more than 70 dB Intermodulation Attenuation is required at a site, an external circulator
should be added to the transmitter output.
