Sennheiser AB 3700 Antenna booster, range: 470-866 MHz - 502196
Product Overview
The Sennheiser AB 3700 is a professional wideband active antenna booster covering 470–866 MHz UHF, providing +20 dB of gain for long antenna cable runs in complex multi-channel wireless installations. Available at Creation Networks for professional AV integrators and touring engineers.
Product Description
The AB 3700 wideband active antenna booster amplifies incoming UHF signals in the 470–866 MHz range with +20 dB of gain, compensating for signal loss over long coaxial cable runs between remote antennas and Sennheiser receivers. Covering an exceptionally wide frequency range, the AB 3700 is compatible with nearly all Sennheiser UHF wireless systems including the 2000, 3000, and 6000 Series as well as G4 receivers. It requires an external DC power supply for operation. The AB 3700 is ideal for large venue and broadcast installations where antennas must be mounted at significant distances from the receiver rack. It can be used alongside the AD 3700 directional active antenna for maximum range extension.
