Here's a pic of the Terk Micro Antenna on my lava. This thing is so small - it is literally about 1x1x0.5 and it works great. You hardly even notice it's up there when you look at the car.

 

I got the Kenwood one which is bigger but I placed mine in the center of my xb with the strip. I also painted the antenna chrome/silver so it matched the rest of my car (I am trying to eliminate all black)

Looks good though. I thought about mounting it in the corner like you did.
