Antenna and dish
Radio on 256 channels: an omni mast talks all round, a dish aimed at its target reaches the satellites and the Moon.
In the game
How to get it
Omni antenna: copper wire radials, a coil and an iron mast. Dish: an aluminium dish round a mirror, a coil and an iron mast. Place it, choose its channel, mode and target on its sheet.
What it is for
Send a signal without a cable, listen to your satellites, link a base on the Moon; the radio bands also stun birds in a farm.
Why it exists
Radio is the only link without a wire: the step from a factory to a space program.
The same text the game shows in its progress tree and on the item's sheet (I).
| Antenna | Recipe | Reach |
|---|---|---|
| Omni antenna | 4 copper wires (radials), a coil, 3 iron ingots (the mast) | all round: near, village, region |
| Dish | 2 aluminium sheets round a mirror, a coil, 3 iron ingots | a 2-degree cone: far, the Moon, satellites |
Both talk on 256 channels: a transmitting antenna sends the value on its signal input, a receiving one gives what it hears. Radio waves do not go through the ground.
