Description The Sennheiser AD 9000 is a directional, active, and intelligent receiving antenna for the Digital 9000 Series EM 9046 receiver. It features the AB 9000 booster, which is directly mounted on the surface of the antenna.The AD 9000 features eight highly selective bandpass filters. Each filter passes frequencies within a 24 MHz frequency window and rejects frequencies outside that range, directly blocking unwanted signals before the first active component. The frequency window can be remotely selected from the EM 9046 receiver.The built-in linear RF amplifier offers very high resistance to intermodulation and compensates for cable losses of up to 14 dB. The booster and EM 9046 receiver work together to monitor the RF cable loss and adjust the gain automatically.FeaturesDirectional receiving antennaAB 9000 active, intelligent antenna boosterEight highly selective filtersAutomatic or manual (without EM 9046) selection of filterHighly linear RF amplifier with typ. 17 dB amplificationN-type connectorsSpecificationsFrequency BandA1-A8 : 470 to 638 MHzRadiation PatternDirectionalAmplification17 dB, ConstantAntenna ConnectorAntenna Output: N-Socket (50 W)Antenna Gain4.6 dBiApex Angle100° (-3 dB)Front-to-Back Ratio≥ 14 dBCurrent Consumption160 mA at 12 V, MaximumOIP3≥ 35 dBmOperating Voltage9 to 18 VDC Feed Via Antenna Cable from EM 9046 ReceiverMounting Thread3/8″-16Dimensions13.0 x 12.7 x 0.9″ / 329x 322 x 23 mmWeight22.0 oz / 625 g
