PowerMax cellphone signal booster -- only slightly larger than those stickers

We know you've seen those commercials at 4 in the morning about those little stickers you put on the back of your battery that boost your cell signal like crazy. Look, we're not saying they're fake (they are), just that aside from not working, maybe they leave something to be desired. Maybe you want a cellphone amp that's something more like a tank. Lucky you, because Digital Antenna's PowerMax cellphone signal booster takes an external wall mountable 7-inch antenna, some power adapters, 30' coax cable, and pumps out some serious GSM/CDMA reception—up to 500% more power.
