The AA-BB selective antenna amplifier is used to amplify the receiving signal in the 655-700MHz band from a wireless microphone (> 15dB). The antenna amplifier should be connected directly to the receiving antenna. Connect the amplifier output with a coaxial cable to the receiver’s antenna input. The AA-BB antenna amplifier compensates for losses in the TASKER RG-58CU coaxial cable up to 35mb, while the BELDEN H155 cable up to 70mb. When two amplifiers are used in series, the distance doubles. The antenna amplifier has been configured to work with the LDU-506 wireless set.
