Radar Tower

The Radar Tower is a building which is used for revealing a circular area on the Map. After being powered, it scans the surrounding area every 5 minutes up to 10 times, increasing in range with each scan. The starting range is based line-of-sight of the tip of the tower, so placing it at the highest elevation possible for maximum efficiency. Any terrain at an elevation higher than its tip or an area blocked by a terrain feature such as the stone arch near the grass field will not be revealed.

It is unlocked via the Quartz Research chain in the M.A.M.

Players should be cautious while climbing the Radar Tower due its tricky ladders, as falls can be fatal.

Coverage
(need to verify) where h = -18 m when referenced to the sea level.
 * A radar tower scans in 3D conical shape, measured from its antenna. Means its range can reach further at ravines or valleys and is reduced for high grounds, even if the high ground is below the radar antenna.
 * The coverage of the radar tower increases with height, so it is always preferred to build it on a high ground, such as on top of a rock spire. It can only scan areas that are at a lower elevation than the tower antenna, and in the line of-sight.
 * Its coverage radius, R (meter), measured on the sea level, based on its building's base height, H (meter), is:

Coverage radius, R is capped at 2120 meters (at sea level) regardless of tower base height, or 4.24km diameter. As such, at least 4 Radar towers are needed to fully reveal the entire map.

Scanning
The Radar Tower starts with a coverage of 50 %, increasing by 5 % per 5 minutes. So it is finished after 50 minutes and can be dismantled afterward. However, it still consumes power after finishing the scan. To bring power to the height where you want to place the Radar Tower, you can bring a Biomass Burner with 200 Solid Biofuel.

Trivia

 * It features a ladder separated into few sections. Using the ladders, engineers can climb up to 76 meters. The remaining height has to be climbed with Jetpack.
 * Both Radar Tower and Space Elevator have the collision box height of 118m, although the latter has a much taller graphical appearance.
 * Its Indicator Light which extends out the sideways near the tip of the tower is not counted towards the collision box.
 * It has been revealed on stream that the ladder of the tower was made by Jace and was a prototype that made it to the game, and will be replaced eventually.
