How many VHF antennas are included in the TH-73A external communication system?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

The TH-73A external communication system is designed with two VHF antennas to enhance its communication capabilities. Having two antennas allows the helicopter to ensure better transmission and reception of signals, improving overall communication reliability. This setup helps in reducing dead zones and maintaining effective connectivity with ground control and other aircraft. In aviation, having multiple antennas can also improve the quality of voice communication and ensure redundancy, which is especially critical during flight operations. The inclusion of two VHF antennas represents a well-thought-out design choice aimed at optimizing operational effectiveness in various environments.
