## Questions & Answers

**Q: Does it plug into the irridium go?  do i need the external adapter to plug this roof top antenna to the irridium go?**
A: I bought this antenna and the adapter to use with my Iridium Go on my RV.  It works great.  There's no metal on the roof of my RV to stick the antenna to, so I glued a large metal washer to the roof, and the antenna sticks to it just fine.
