Basic Qualification · B-007 Radio wave propagation · B-007-001-001
What type of wave propagation usually occurs between two nearby VHF transceivers?
- AAuroral
- BLine-of-sight
- CDucting
- DIonospheric
Correct answer: B — Line-of-sight. From the official ISED question bank, verified word for word.
Why
VHF signals travel in straight lines like light, so two nearby radios usually communicate only if they can see each other directly without hills or buildings blocking the path. The full explanation — and one for every question — is in Pro.
