A few months back I posted about my ham and GMRS radio setups in the Jeep.
A few people commented on the head unit setup, so I thought I would share a few more details.
I have a Yaesu FTM-400 XDR. The base unit is mounted under the drivers seat, and the head unit is mounted on a custom bracket on the dash. The bracket started life as an off-the-shelf piece that holds a CB mic and attaches to the passenger side dash grab bar. I cut a T shaped piece of sheet metal that would allow for mounting the FTM head unit and three mics. The T is mounted upside down and the end rounded where the FTM mounts. It was all painted black, and I used pop rivets to mount the mic holders.
Here are some pics of the mount. I hope this helps others build a custom bracket for their ham, GSRM, or CB setups.
I currently run this FTM-400, a Midland MXT400, and a Midland 75-822 CB.
