VHF/UHF Beacons
Beacons on 144 MHz and higher frequencies are mainly used to identify tropospheric radio propagation openings. It is not uncommon for VHF and UHF beacons to use directional antennas. Frequencies set aside for beacons on VHF and UHF bands vary widely in different ITU regions and countries.
| Band | Beacon Sub-band (MHz) | ||
|---|---|---|---|
| ITU Region 1 | ITU Region 2 | ITU Region 3 | |
| 2 m | 144.400-144.490 | 144.275–144.300 | Unknown |
| 1.25 m | N/A | 222.050–222.060 | N/A |
| 70 cm | 432.800-432.990 | 432.300–432.400 | Unknown |
| 33 cm | N/A | Varies Locally | N/A |
| 23 cm | 1,296.800-1,296.990 | 1,296.070-1,296.080 | Unknown |
| 13 cm | 2,320.800-2,320.990 | 2,304.300-2,304.400 | Unknown |
The beacon sub-bands in the United Kingdom, also reflect IARU Region 1 recommendations.
