I've posted this picture again in this new "Mobile Setups" thread :-)
The kit is sitting on the rear parcel shelf of my Renault Megane, with the standard RadarBox antenna in the centre of the roof. The car is facing the runway, so I was able to stand at the rear of the car and watch RadarBox and the aircraft at the same time. The car hatchback keeps some of the light off the laptop screen, but I did find that a white map background with black aircraft labels worked best.

Below: Screen capture - ADS-B traffic only selected - 39 aircraft with full ADS-B information in the list. You can see why I had to use the altitude filter to just see the low level traffic!
