## Key points

- VHF radio operates on a line-of-sight principle, meaning physical obstructions like hills can block transmission.
- In areas without cell coverage, VHF radio is often the primary communication tool, making its limitations critical to understand.
- Fixed-mount VHF radios on boats may be unable to receive signals if the transmitting party is on the other side of terrain obstacles.
