the antenna pulled out while being raced, it was laying on the carpet. is there a small soldering iron to use. my guns tip is too big for the job. and it seems like the other soldering guns ive looked at have had too big of a tip aswell. it broke right at the board. i dont want to try it with mine and make a bad issue worse.

You'll need an iron with a pointed tip. My iron came with a flat tip, but I picked up a set of extra tips for ~$4 that came with a pointed one.
