I installed a Motorola XPR5550 in my vehicle. I attached a handheld control head (HCH), which is kept the in the center console for easy storage. Radio chassis is mounted under the driver seat in a storage box. The vehicle battery is under the passenger seat in the same style box. I routed the power cables under the center console to the driver & passenger side. The HCH cables are routed up the center where the shifter is into the center console.
I chose a Laird ETRAB4303 phantom antenna for ease of parking in garages & a low profile. I keep a Comet UHF antenna in the back of the truck to attach for road trips.
I am installing the antenna this weekend, I will post photos when I am done.
