How big is a marine satellite dish?

If you’re thinking of adding satellite TV or internet to your boat, you’re probably wondering how big and heavy the equipment is. It’s a logical thing to worry about. I have good news for you… this stuff isn’t as big or heavy as you think.

Satellite TV (TVRO)

There are many different sizes of satellite TV antennas for boats. The bigger they are, the more sensitive they are that that means better reception further offshore. However, for pleasure craft based in the US, we tend to look at two models.


The Intellian i3 is a general purpose satellite TV antenna that can focus on one satellite at a time. It’s a good choice for smaller boats, not just because of its size but its relatively lower price.

What you need to know here is that the internal dish itself is 37cm (14.56″.) The dish including the outer white radome is 43 cm x 44 cm (16.9″ x 17.3″) and it weighs 9 kg (19.8 lbs.) That last number surprises people because they think it’s going to be a lot higher. Satellite TV antennas don’t add a lot of weight to the boat and I’m sure you’ll agree that’s a good thing.


To see multiple DIRECTV satellites, you’ll need Intellian’s s6HD system. It is a little bigger, but it will give you the same experience on the water that you get on land, with the same speed when you change channels no matter which satellite you need.

The s6HD is a little larger. The antenna inside is 60cm (23.6″) while the outer dimensions are 70 cm x 72 cm (27.5″ x 28.3″.) It weighs in at 21.6 kg (47.7 Ibs) meaning it may take a little more planning to get it mounted.

Satellite Internet (VSAT)

Internet on your boat is a reality. With satellite internet, you can stay connected 24/7 and it’s just as easy as it would be at home. There are two antennas commonly used for VSAT.

v45C and v60E

Intellian’s new VSAT dishes are so new, they don’t have specs yet. But, the v45C is fairly comparable to its i4 dish, which is 50 cm x 54 cm (19.7″ x 21.2″) and weighs 11.6 kg (25.5 lbs.) Its v60E dish is fairly comparable to the s6HD, and those specs are above.
