External Cellular Antenna Location


The phone (iPhone 5) is already connected via Bluetooth and works fine hands-free, but I would like to have external antenna for the booster due to travel in remote areas where phone reception is spotty.
The car is: 2008 E320 BlueTec, WDBUF22X58B236356 and has code 414 tilt / slide glass sunroof.
I am thinking best location would be in front of the sunroof, half way in-between sunroof and the windshield framing.
Has anyone here done it, if so any comments?
