The Sennheiser GA 3030-AM is an antenna front-mounting kit for rack-mounted wireless microphone receivers. It lets you move the receive antennas of a rack unit from the rear panel to the front of the rack, which gives the antennas a clearer line of sight to the stage and keeps them out of the cluttered, metal-screened space behind the equipment. Sennheiser lists it for the EM 3031, EM 3032 and EM 3532 receivers and the SR 3054 and SR 3056 transmitters, and it is widely used with 2000 and 3000 series racks. The kit contains two short BNC connecting cables (RG-58 type coax with moulded BNC plugs at one end and bulkhead BNC sockets at the other), two front-mounting antenna brackets and four screws, so the antennas plug straight into the front of the rack ears. It weighs about 86 g and carries Sennheiser's 2-year warranty. Antennas and receivers are not included; this is the mounting and cabling kit only.
