Antenna

From HBM's Nuclear Tech Wiki

Antennas are structures that are comprised of decoration blocks and have one loot chest.

Where to find

They generate in the plains, forest, desert, swampland, and extreme hills biomes.

Loot

The loot chest they have contains common items, such as steel, titanium, or Nuka Cola.

The blocks themselves also can be harvested and shredded, returning small amounts of steel and beryllium powder that can be made into ingots. The deco blocks can be broken down into ingots using an anvil.

Refurbishing

Tape recorders and satellite dishes have no function outside of aesthetic, they just make your world look cooler. Besides, the structure is practically undamaged, so there is nothing to refurbish in the first place.
