Cantenna

Hi,

I was looking at

I really don't understand why you need to create electrical contact between the n connector and the can (eg. i've seen some just scrape the paint off and screw on and others solder the n connector to the can)?

The copper that sticks up in the can is hooked up to the center connector of the n connector, then the can has electrical contact on the outside of the n connector(not sure what that part is called). The outer coax shielding connects in my knowledge to that outer part of the n connector and the inner core of the coax connects to the center contact in the n connector.

Does this not mean that ultimately the can is being connected to ground on the wireless card?

What is the point of the can being connected to the ground? Is this to shield the copper wire inside the cantenna from signals other than what is coming in the front?

Sorry if this is not clear. I have only a very little bit of knowledge on the topic and i'm trying to figure out the basic logic of the design. I'm basically looking to find out how the can and copper wire in the can are interacting in basic terms.

Thanks a lot, Stephen
