I am living in a cell dead zone temporarily and thanks to Arc’s Freedom Antenna, I can at least get a few more bars of signal strength and actually hear my callers. The antenna is about four inches high and has various cables to attach to a few different phones — you can search the company’s Web site and find out if yours is covered. In my case, the Razr has a small rubber plug on the back that pops out and can be connected. It is a bit cumbersome, and I still leave the antenna by the window to pick up the best signal, but the arrangement works. The antenna is less than $30 at major online retailers.
