船用天线

它是什么？ An Antenna is a piece of equipment that receives information via radio frequencies. There are different antennas for different purposes, such as internet, phonecalls, television and radio etc.

A Marine Antenna is used at sea and differs from its land based cousins in some essential ways.

The design must be able to withstand the harsh conditions at sea.
A ship moves in all directions with the waves - requiring satellite antennas to make realtime counter-moves in two directions in order to fix its position towards a satellite.
Electrical grounding at sea - a ship is not able to ground any electronics as is doable on land. This requires products to be double isolated in order to not cause interference with other sensitive equipment on board.

It is always recommended, and often law, to make sure all equipment used in marine environments are classified for marine use. 这些特殊要求通常使船舶设备比陆基设备更昂贵，这是有充分理由的。安全第一。

A marine antenna is normally installed at the highest possible location on the ship in order to get the best possible reception.

海上电视广播

Almost two thirds of the world's surface is covered with water. A海上船员福利的重要部分是看电视和听广播的能力。对于在深海或大洋中航行的船只，当今唯一的选择是安装昂贵的卫星天线并订购昂贵的电视和/或互联网服务。

However, in most situations, when vessels are closer to land, there are plenty of TV and radio channels available as so called free-to-air channels. These are broadcasted from big landbased antennas providing signals on land, but also shorelines and miles into the sea. This is also called communal or terestrial TV and radio.

与卫星系统相比，安装免费的电视/广播系统要便宜得多。实际上，在大多数情况下，当安装昂贵的卫星系统时，您还会发现包含免费的空中系统作为备份。
