I have an HS200 switch, which is in a metal work gang box and has a metal face place.  Not ideal to have so much metal, especially the faceplate, but needed for the location on a work bench in my garage.  I get random signal strength issues with the switch, where it'll drop off the network and then come back on the network. I'm pretty sure the metal box and cover are messing with the HS200's WiFi reception.  Is there a way to extend the WiFi antenna for the HS200?  I noticed the HS200 has a small piece of flat metal that comes out of its housing near the bottom mounting screw hole.  Is this the antenna for the HS200?  If so, I'm thinking I could I solder or attach a small piece of copper wire to that piece of metal and run that outside the metal enclosure to get the HS200 better WiFi reception.  If that's not the antenna, where is it and can I get to it?
