The Wilson 801280 AG Pro 75dB amplifier is the newest amplifier from Wilson Electronics. It features a massive 75dB of gain - making it by far the most powerful consumer amplifier available. When combined with antennas and cable, the Wilson 801280 will cover up to 30,000 sq ft of wireless coverage. This makes the Wilson 801280 perfect for large offices, warehouses or outdoor spaces such as a ranch or camp ground. The AG Pro 75 is the highest gain signal booster Wilson has released to date. The unit delivers a maximum gain of 75dB at 1900 MHz and 70dB at 800 MHz. The product includes Wilson's patented oscillation and cell site overload protection, and proximity detection technologies to prevent interference on the cellular network. It works with all cellular devices on all North American service provider networks (except Nextel/iDEN and 4G).
