Plug this MFJ "back-of-radio" antenna into your 2 Meter/440 MHz mobile or base rig in your shack. Fold antenna vertically and youre ready to operate -- no more coax tangles, finding a place to put a magnet mount or putting up an outside antenna. It may not be a ten element yagi but it'll get you out in a hurry! Use with your rig on your desk at home, testing used gear at hamfests, as an efficient mobile fold-over antenna with gain, hamfest talk-ins, etc.
