FCC Technician Exam Question Of The Day (T3A02)

Q) Why are UHF signals often more effective from inside buildings than VHF signals?

A) The shorter wavelength allows them to more easily penetrate the structure of buildings


NJ2X Notes:
The higher the frequency, the shorter the wavelength, and the smaller the opening required to pass signals through.
