Sennheiser - AD 3700

The Sennheiser AD 3700 is a broadband active directional antenna developed for demanding RF environments such as broadcast, live touring and professional fixed installations. Designed to operate over an extended frequency range of 470 to 866 MHz, it significantly improves the reception quality and stability of compatible Sennheiser wireless systems.

Its standard 50 Ω impedance ensures perfect compatibility with professional RF infrastructures. This antenna is designed exclusively for EM 3731, EM 3732, EM 2000, EM 2050 and EM 6000 receivers, guaranteeing optimum integration into the brand's top-of-the-range HF systems.
