Maritime TVRO / VSAT · Stabilized antennas
Two-axis V Series from 33 cm to three-axis X Series at 105 cm. Each model is chosen against the weakest EIRP contour on your route — then delivered with the controller and the headend that reaches the cabins.
01 — Selection table
Minimum EIRP is the weakest satellite signal each unit can hold — lower is better. Read down the column until you find the number below your route's weakest contour, then stop: that is the model you need.
| Model | Platform | Radome | Weight | Min. EIRP | Recommended route | |
|---|---|---|---|---|---|---|
| V3 | 2-axis | 33 cm | 5 kg | 50 dBW | Inland / near-coast | Spec → |
| V4 | 2-axis | 45 cm | 12 kg | 48 dBW | Fishing vessels, tugs | Spec → |
| V6 | 2-axis | 60 cm | 20 kg | 46 / 47 dBW | Regional routes | Spec → |
| V7 | 2-axis | 75 cm | 32 kg | 44 dBW | Coastal passages | Spec → |
| X6 | 3-axis | 64 cm | 37 kg | 46 dBW | Yachts, mid-size vessels | Spec → |
| X8 | 3-axis | 85 cm | 80 kg | 43 dBW | Ocean passages | Spec → |
| X10 | 3-axis | 105 cm | 125 kg | 41 dBW | Long haul, maximum margin | Spec → |

TVRO stands for Television Receive Only. On a vessel it is a stabilized satellite antenna that tracks a broadcast satellite while the ship moves, feeding a receiver and then a distribution system so the crew or passengers can watch television at sea.
TVRO is receive-only and is used for broadcast television. VSAT is two-way and is used for internet, voice, video and remote monitoring. Many vessels carry both, and the two systems share the same antenna-control philosophy.
On a vessel, streaming depends on a metered satellite link that is shared with operations. Broadcast television arrives on a receive-only path that costs nothing per hour and does not compete for that bandwidth — which is why TVRO is still the default for crew welfare.
Yes on the distribution side: an IPTV headend can carry different menus and different channel lists per group, while a CATV headend broadcasts one plan to every connected television. The antenna and receiver are shared in both cases.
By route and by signal margin. The V Series is a 2-axis platform in 33–75 cm sizes, 5–32 kg, for coastal and regional routes. The X Series is a 3-axis platform in 64–105 cm sizes, 37–125 kg, for ocean passages and heel-heavy hulls. Bigger aperture needs a lower minimum EIRP, which means it can hold a weaker satellite.
It is the weakest satellite downlink the antenna can work with, expressed in dBW. Lower is better: a V3 handles 50 dBW, a V7 handles 44 dBW, an X10 handles 41 dBW. Match it against the footprint of the satellite you intend to watch on your route.
