PowerMax Cellphone Signal Booster

I’ve seen a lot of similar products, but Digital Antenna’s PowerMax will really help you out when in need of sending (or receiving) some SMS messages while sailing (too far) offshore….
“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.”
