Question for shaved external antennae....

[RamThis]

What internal antenna do you guys use when you shave the external mast antenna? I want to do this to ALL my vehicles. I've seen one from AutoLok and a couple other places, that go either in your headliner (not on these trucks though lol) or they stick to the windshield right above the rearview, looks like a small box with a couple small antenna rods sticking out both sides.

I have to try one in my Honda since I shaved the roof mounted antenna when I added in my sunroof, but I wanted to know what you guys have used and gets good reception like the stock mast????
