Many vessels are equipped with dedicated HF-SSB equipment, a stand-alone 27MHz marine radio, and VHF marine equipment, with the 27 MHz gear being used for backup or supplementary purposes. It is due to favorable propagation characteristics over open water that low power 26-30 MHz marine systems remain popular.

Many vessels are equipped with dedicated HF-SSB equipment, a stand-alone 27MHz marine radio, and VHF marine equipment, with the 27 MHz gear being used for backup or supplementary purposes. It is due to favorable propagation characteristics over open water that low power 26-30 MHz marine systems remain popular. See the other sections of this article for information regarding 11 meter marine radio bands in other countries. </ins></div></td></tr>
