I saw some stuff on here & eham a few months back on stealth apartment antenna projects. There are a few other sites out there that I can't remember, just google 'ham radio apartment antenna design'. dxzone.com has some stuff. ARRL & other organizations have good antenna books. I have one of the ARRL ones, it's a good learning tool. The 7000 actually puts out about the same amount of heat as a bigger radio, it's just that all the circuits are crammed in a very small area with a small heatsink. A small fan blowing on the rig will help.
