BG4LZP Can I use my handheld radio to operate a repeater? If so, just buy a good quality vehicle antenna, suction cup mount, or magnetic base, along with a vehicle-specific feedline. The feedline should be calculated for the correct length and used to connect the handheld radio to the repeater. Shorter feedlines are preferable, as they minimize signal loss. Handheld radios have limited power output, so minimizing losses is important.
