Marine UHF SATCOM antennae

Marine UHF SATCOM antennae

(OP)
Can anyone give me details of lightweight UHF SATCOM antennae for use in the harsh marine environment as opposed to aircraft?

RE: Marine UHF SATCOM antennae

To which "UHF SatCom" band are you referring ?

RE: Marine UHF SATCOM antennae

(OP)
243-270 and 292-318MHz and between 5 and 25kHz Bandwidth

RE: Marine UHF SATCOM antennae

Okay - UHF MilSatCom.

Most of the major military antenna suppliers will have marine qualified products.  You will need to decide on your own requirements for gain versus coverage - usually hemispherical coverage (or more, due to pitch and roll) is required and that tends to put limits on the gain unless you decide on an active solution ($).

Most "boats" will have a large mast structure that tends to 'get in the way'.  You need to decide if you need to use a multiple antenna system, accept shadowing, or find a practical way to install your antenna at the very top of the mast (usually impractical).

There much more we could talk about - but perhaps off-line.

Probably won't go down the active route because of weight and cost implications. I'm only at the budget stage at the moment and so looking for ball park figures.

Thanks for your help and the links, which at first glance seem very useful.
