Stupid Question


Is there a whole drilled in the glass to hold that cell antenna mount?

If so whats a back window cost?

Nope....No hole. Just grab a good hold of it and rip it off. Both sides of course. It just transmits through the glass.

No hole in the glass. Electrically, a glass mounted antenna works like a capacitor: two conductors separated by an insulator (the glass)

Glass is an excellent electrical insualtor.

So if it was an insulator how would current flow?

That'* the idea. It'* not suposed to conduct.

Without getting too technical, because RF transmissions are a sine wave, the signal passes through the glass because of the capacitor-like properties of the antenna.



This is a very basic and typical schematic of an antenna found through a Google search. C1 is a capacitor on the antenna input. This is essentially your window.
