Q

Describing VHF transmissions as "line of sight" does not mean:

🔍 Key Concepts

• VHF radio is line-of-sight – what does that actually mean in terms of distance and obstacles? • Antenna height and radio horizon – how does raising the antenna affect range? • Typical VHF ranges: ship-to-ship vs ship-to-shore with tall coast station antennas.

💭 Think About

• For each option, ask: would this be true or false for real VHF line-of-sight behavior? • Think about whether antenna height (ship and shore) changes how far you can "see" over the horizon with radio waves. • Consider if VHF can only reach as far as you can visually see from the bridge, or if it can often go farther.

✅ Before You Answer

• Be clear on whether antenna height affects the radius of propagation. • Recall if coast stations often have much greater range than 10 NM and why that is. • Decide which statement does NOT correctly describe real line-of-sight VHF behavior, even if it sounds reasonable.
