🔍 Key Concepts

• HF (High Frequency) vs VHF (Very High Frequency) power levels in aircraft radios • Typical installed RF output power ranges for airborne HF sets • Typical installed RF output power ranges for marine/aviation VHF sets

💭 Think About

• Think about which system (HF or VHF) is normally used for long‑range communications and would therefore need more power. • Recall from your studies: are HF aircraft sets usually in the tens of watts or in the hundreds of watts range? What about VHF? • Compare the choices: which one shows HF power being significantly higher than VHF, matching their usual operational roles?

✅ Before You Answer

• Make sure the option you choose has HF power > VHF power, not the other way around. • Check whether the HF value you pick is a realistic installed aircraft HF output (often around a few hundred watts, not just a few tens). • Confirm that the VHF value is in the typical 25–50 watt class commonly used for line‑of‑sight communications.
