Motorola's first solid state 450 car phone, the MK, used a 50 W 150 MHz PA

The worst is suppression of 150MHz, it is almost impossible to
suppress it. Bought some UK commercial integrated modules for 432MHz
which was fed from 144MHz 1W, had a 20W amplifier within a very well
screened and silvered box, but radiation on 144MHz were almost
impossible to suppress, the only way out was to place it deep at the
lowest point of the basement with ferrite chokes on the cables
