However as you’ve noted, it’s bare metal so it could short something, I certainly would not take that risk myself. So you will need to use something like insulation tape to cover the bare metal before you use it. After that it should be fine to use.
OK, thanks. I’ll make the decision after I look inside the NC10 and see what I’m dealing with. It’s not like that 3rd antenna is likely to help much on my trip anyway as I’m not likely to run into a lot of N networks on the road. That’s more for home.
It’s just that I was going to swap the wireless card, attach the antenna, and swap the hard drive all at the same time so I’d only have to break into the case once. Not a big deal to break it open again later for the antenna if I need to. I imagine that opening the case the first time is the hard part. After that it probably comes apart more easily.
