Hi,
I've seen a couple different types of antennas. I was wondering if anyone has a feel for the relative advantages of each. Can I really just solder a 4" wire to the antenna pin? Also, what kind of orientation should the wire be at relative to the orientation of the receiving module's antenna?
Here's a picture of one using just wire and one using an actual SMA antenna.
