If you operate your station with indoor antennas, what precautions should you take when you install them?
- ALocate the antennas as far away as possible from living spaces that will be occupied while you are operating
- BPosition the antennas parallel to electrical power wires to take advantage of parasitic effects
- CPosition the antennas along the edge a wall where it meets the floor or ceiling to reduce parasitic radiation
- DLocate the antennas close to your operating position to minimize transmission line length
Correct answer: A — Locate the antennas as far away as possible from living spaces that will be occupied while you are operating. From the official ISED question bank, verified word for word.
Why
Radio waves carry energy that can be harmful if you are too close for long periods, so placing indoor antennas far from where people live or sit reduces your exposure to this radiation. The full explanation — and one for every question — is in Pro.
