That antenna was specifically made for a CP200 radio, using that antenna on another radio like the BPR40, will run the risk of burning out the power amplifier. It’s not a question of “if”, but of “when” the power amplifier will burn out. Use only the antenna that was specifically designed for the BPR40.
