How far can a ham radio reach? There is no single fixed answer because range depends on the frequency band, antenna, height, transmit power, terrain, and propagation conditions.
Two handheld radios at ground level may typically communicate only a few kilometers because buildings, hills, and trees block VHF and UHF signals. Moving to a higher location can greatly improve line-of-sight and increase the range. A mobile or base station with a better antenna and higher power can often cover tens of kilometers. A repeater placed on a tall tower or hill can extend communication much farther by receiving a weak signal and retransmitting it over a larger area. HF radio works differently. Its signals can interact with the ionosphere and return to Earth hundreds or even thousands of kilometers away.
Amateur radio satellites can also connect stations across very large distances.
This is why ham radio can be used for everything from local handheld communication to worldwide contacts.
