The included accessories

MA-203 R82323 amplifier is designed to strengthen FM radio signals and television channels in the VHF and UHF bands - in medium and large antenna installations. It has 5 band inputs: 1 x FM/VHF I, 1 x VHF III, and 3 x UHF. Each input has separate gain adjustment, additionally after combining signals of FM/VHF I + VHF III and those from three UHF inputs it is possible to suppress them in selected path by using 10 dB attenuator.
UHF signals are combined in two steps, first from two inputs and then with the third input. It allows to choose optimum inputs for lower and higher signals. The amplifier features high maximum output level: 119 dBuV (VHF) and 121 dBuV (UHF).
Main features
  • separate FM+VHF and UHF paths,
  • gain correction with interstage attenuators,
  • protection against DC overload (LED signaling),
  • possibility of powering preamplifiers via individual inputs,
  • built-in test output,
  • durable cast-metal housing.
