The Tower Appears To Hold Lots Of Importance For The Team’s Plans

TheStranger Thingsseason 5 trailer makes a point tocontinuously highlight the radio tower in town. This starts with Steve and Dustin at WSQK doing something with a satellite on top of their van. In addition, a voice counts down to a “burn” happening, with the numbers rising on what appears to be a radio inside of the van.

These numbers continue to rise throughout the trailer, withone shot at 1:42 showing the radio tower itself.

The Radio Tower Could Be Used As A Weapon In Stranger Things Season 5

Powerful Radio Wavelengths Can Cause Fires

Based on these context clues, it seems likethe group is amplifying radio waves to start a fire. This is physically possible in real life, with extremely powerful radio wavelengths able to ignite certain objects or make sparks. Some radio waves have been applied medically to heat deep body tissue, too, making a fire possible with enough power.

Given the burning that was explicitly talked about at the start of the trailer, it seems like the team really is using radio waves to set fires. Sinceflames have been shown to be an effective method of curbing the spread of the Upside Down’s vines, it only makes sense they’d find a creative way to make them.

Season 5, episode 5 is titled “Chapter 5: Shock Jock,” hinting at when the radio tower will be a key focus of the season.

AsStranger Thingsseason 5’s storyplays out,the team will be using more creative means than before to fight Vecna. The radio wavelengths appear to be one important method, something that could be a primary focus of their efforts going forward. As the battle for Hawkins commences, they’ll need to do everything they can to save their town.
