What does the power inverter group supply for proper antenna operation?

The power inverter group is crucial for providing the necessary electrical power for radar systems, especially in military or aviation applications. For proper antenna operation, it supplies specific DC voltages that are essential for powering radar systems effectively.

In this case, the correct answer indicates that the inverter group supplies DC voltages of 115V at 400Hz and 26V at 400Hz. These voltage levels are particularly important because radar systems often operate at high frequency, which requires precise voltage supply to ensure optimal performance and communication between radar components. The 115V, especially at a frequency of 400Hz, is commonly used in avionics and military applications, allowing the equipment to function reliably under various conditions.

Understanding the specific voltage requirements is critical, as alternative voltage supplies could lead to inefficient operation or even equipment damage. Therefore, the inverter group's ability to supply these particular DC voltages is essential for ensuring the reliable functioning of radar antennas.
