Which statement best describes the propagation and operating considerations when comparing VHF/UHF nets with HF nets?

• A. VHF/UHF are line-of-sight with direct path; HF uses ionospheric propagation enabling long-range; nets may require different frequencies, time-of-day planning, and message routing.
• B. HF nets are line-of-sight with direct path; VHF/UHF rely on ionospheric propagation.
• C. V/UHF require satellite relays; HF nets are always local.
• D. V/UHF and HF have identical propagation, so frequency planning is unnecessary.

Answer: (A)
