    • HAM Radio (RF)

    UHF and VHF are particular radio frequencies that are used by two-way radios and communication systems.


    UHF (Ultra high frequency) Shorter radio waves make it best-suited for wireless and indoor use, where there are more penetrable obstacles. VHF (Very high frequency) Excellent for outdoor use; construction workers, aviators, and boat captains rely on VHF radios on their crafts.
