Question
What is the effect of fog and rain on signals in the 10 meter and 6 meter bands?
Answer Options
- A) Absorption
- B) There is little effect
- C) Deflection
- D) Range increase
Correct Answer: B
Explanation
The 10-meter (28 MHz) and 6-meter (50 MHz) bands are low enough in frequency that their wavelengths are relatively long compared to the size of raindrops and fog droplets. Therefore, unlike the microwave bands (T3A07), precipitation does not significantly absorb or scatter signals at these frequencies.
For practical purposes, there is little effect on the signal strength or propagation on these bands due to fog or rain. This makes these bands relatively reliable in terms of atmospheric weather conditions, allowing signals to pass through precipitation largely unhindered.
