Selection guides · 4
Every TVRO and connectivity quotation comes down to four choices: how many axes the antenna needs, whether television reaches the cabins on coax or on the LAN, which control unit the vessel gets, and which link carries the traffic where. Each guide below is written against the manufacturer's own catalogue figures, with the page reference on the page.
The difference is not "better vs worse" — it is which axis carries the vessel's heel. A 2-axis mount covers elevation and azimuth and lets automatic skew handle polarization; a 3-axis mount adds a cross-level axis so the dish stays square to the satellite while the ship leans. Below is what that costs in weight, in elevation range and in the footprint you can hold.
Both routes start the same way — antenna, ACU, receiver — and both end at a television in a cabin. What changes in the middle decides the cost, the retrofit risk and what the crew can actually watch.

Read →The ACU is the box that powers the antenna, holds the satellite parameters and hands the L-band signal downstream. The catalogue documents exactly four functions where Basic and Advanced differ — and only three of them are actually different.
A vessel rarely needs one link — it needs the cheapest link that works at the position it is in. The three options differ mainly in range, and the design work is in the handover between them rather than in any single box.
Send the vessel type, the route and the satellite. The reply covers all four decisions and the cable schedule that follows from them.
