In another post, it was suggested I could "hide" my window mount by placing it near my visor. Today, while a LEO was to my driver side rear, I pulled my RD off from the middle of the window (Ka @ 3 bars) and holding it in my hand, moved it around my windshield. As I moved towards the visor area, I lost signal all together. Moved it back to the middle, 3 bars. I really don't think it would be well advised to "hide" a windshield mount, based on a live (real world) test. If it hindered performance here, it might hinder in other scenarios.
