Hi Rob!
Sorry for the late reply. As others have mentioned, these adapters are
quite common. You'll need something close to 12~13.8vdc, @ 700ma. Possibly
Radio Shack Cat #273-1776. Make SURE the center pin is positive, and the
outer barrel is negative. As for the antenna, Radio Shack has them also.
Cat #20-034 would be a good choice. They also have the 90 degree, BNC
adapter that you might need.
