How to Make a Silly Beer Can Antenna at Home

on

Sometimes, the best DIY projects are the ones that combine resourcefulness, silliness, and maybe a leftover can from last night’s six-pack. If you’ve ever found yourself with poor TV or radio reception, or you just want to experiment with antennas, here’s a lighthearted guide to building your very own beer can antenna using just a couple of household items.

What You’ll Need

  • One (or two) empty beer cans – Rinsed out, of course. Soda cans work too, but beer cans feel more authentic.
  • A length of coaxial cable – The kind used for cable TV. Ideally with an F-connector on one end.
  • Some tape, zip ties, or hot glue – Whatever you’ve got to hold it together.
  • A TV or radio with a coax input – To test your new creation.
  • A healthy sense of humor – Mandatory.

Step 1: Prepare the Cans

Drink responsibly, then clean your cans. For best results, use two cans of the same size. You’ll be cutting or poking a small hole in them later, so make sure there are no sharp edges. A file or sandpaper helps to smooth them down.

Step 2: Strip the Coax Cable

Take your coax cable and carefully strip back the insulation at the end that doesn’t have a connector. You’ll expose two key parts:

  • The center conductor (the copper wire inside).
  • The outer braided shield (like a little metal mesh).

Keep them separated so they don’t short out.

Step 3: Connect the Cans

Here comes the fun part:

  • Attach the center conductor to one can. A small hole poked in the bottom helps you wedge it in place.
  • Attach the braided shield to the other can in the same way.

Now you’ve got two cans sticking out from the end of your coax. Space them apart by about an inch or so. Tape or glue them to a scrap of cardboard or wood if you want a sturdier setup.

Step 4: Hook It Up

Screw the coax connector into your TV (or radio). Switch to “antenna” or “air” mode if you’re using a TV. Position your cans by a window, high up, or in whatever direction you think the signal’s coming from. You may have to do some silly adjustments—rotating the cans like satellite dishes—until you get the best reception.

Step 5: Bask in Your Achievement

Congratulations, you’ve built a beer can antenna! Not only does it look hilarious, but it can actually pull in a surprising number of channels if you’re in range of broadcast towers. Plus, you’ve recycled some aluminum in the most chaotic-good way possible.

Bonus: Get Experimental

Want to take things further?

  • Try different can sizes (tallboys, stubby cans, or even a Red Bull can for a “high-energy” antenna).
  • Experiment with the distance between cans.
  • Paint or decorate your antenna for added flair.

Final Thoughts

This silly project is equal parts functional, fun, and frugal. Whether you’re testing your inner MacGyver, looking to impress your friends, or just trying to catch the local news without paying for cable, a beer can antenna proves that sometimes the simplest solutions are also the quirkiest.
