Are you receiving the “wrong altitude” error when placing antennas in Raft? If you’re wondering how to place your Raft antennas correctly, you’ve come to the right place.
We’ll show you how high to place the antennas and receiver, saving you from building a monstrous tower that doesn’t resolve the issue.
For a quick overview of how to fix the Raft wrong altitude issue, here’s how to do it:
- Place 3 antennas and 1 receiver at least two blocks high
- Place your antennas at least 3 blocks apart from each other
- A green light will show at the top of the antennas to indicate you’ve done it correctly
The Problem
Creating the receiver in Raft is quite an accomplishment. You’ll need to research the Blueprint: Receiver at the Research table then place three antennas down.
However, most players place the antennas and then find they’re receiving a notification saying “wrong altitude”. Naturally, you’d think placing the antennas higher up on your raft would resolve the issue.

However, placing the antenna as high as you can won’t resolve the issue, and will simply waste your time and resources, without actually solving anything.
The Solution

First, you’ll need to make sure you place your Raft antennas around two blocks high. If you have an upper level to your Raft, this is a good option.

Next, you need to place your antennas at least three blocks apart from each other. Ideally, a 7×4 second floor is a perfect solution to your “antenna wrong altitude” problem.
You will need to place the receiver on the same floor as the 3 antennas. Once the placement is correct, you’ll see a green light appear above the antennas.
Once you have properly placed the antennas on Raft, you can start using the receiver to track down bigger islands that are rich in resources, as well as to help you progress through the game’s story.
