What frequency mode does the EF Johnson 5112 operate in?

• A. VHF
• B. HF
• C. UHF
• D. SHF

Answer: (A)

The EF Johnson 5112 operates in the Very High Frequency (VHF) band. This mode is commonly used for various communication systems, including land mobile communication, as it provides a good balance between range and clarity of voice transmission. VHF frequencies are typically in the range of 30 MHz to 300 MHz, which allows for effective line-of-sight communication and relatively low susceptibility to interference compared to other frequency bands. The VHF mode is particularly suitable for many public safety and emergency services communications, which aligns with the typical applications of the EF Johnson 5112.
