I have a Kenwood TM-D700 setup on my motorcycle. The radio itself is mounted in the trunk. The display head is up front (covered with a ziploc bag for those rainy days) using a RAM mount. The antenna is a Diamond SG-M510 2m/70cm Dual-Band Mobile Antenna mounted with a custom mount. The antenna is a 1/2 wavelength on 2m which makes it ideal for use in this application with a limited ground-plane. It works well on the motorcycle because of it's fold over hinge design that will let me fold the antenna down when I put a cover on the bike.
