What is the effect of fog and rain on signals in the 10 meter and 6 meter bands?

• A. A. Absorption
• B. B. There is little effect
• C. C. Deflection
• D. D. Range increase

Answer: (B)

Fog and rain primarily affect radio signals through absorption, especially at higher frequencies. However, in the context of the 10 meter and 6 meter bands, which operate at UHF and VHF frequencies, the impact of weather conditions like fog and rain is relatively minimal compared to higher frequency bands. Signals in the 10 meter and 6 meter bands can propagate reasonably well through these atmospheric conditions. While there is some degree of absorption due to moisture in the air, it does not significantly hinder communication in these frequency ranges when compared to lower frequency bands. Thus, claiming that there is little effect from fog and rain acknowledges the resilience of these bands to such environmental factors, allowing for continued operation and communication despite adverse weather conditions.
