A radio antenna, sometimes called an aerial, is a metal rod or dish that catches radio waves, transforming these into electrical signals that your radio or TV can interpret as information, like music or video. Thankfully, the hardware behind radio antennas is fairly simple and inexpensive, which will make fixing your antenna an easy matter.

Step 1: Analyze the Break in Your Antenna
Many radio antennas have telescoping links that allow it to extend or detract. Find the link directly below the break in your antenna. This is likely the best place for you to apply your aluminum foil.
Step 2: Cut a Single, Continuous Sheet of Aluminum Foil
The radio signals in the air must be conducted by unbroken piece of foil. The signal cannot transmit across gaps in the metal, so using a single piece will help you prevent these from forming.
Step 3: Rejoin the Broken Part of the Antenna With Your Foil
Wrap your foil around the broken bottom of the top piece of your antenna until both parts are firmly joined. Due to aluminum foil's malleable nature, your antenna will probably be somewhat flimsy until you apply your duct tape.
Step 4: Wrap Duct Tape Around Your Foil
This will insulate your break from the elements as well as strengthen the connection bridging the break in your antenna. Continue wrapping your duct tape until the foil is completely covered.
Step 5: Check Quality and Adjust As Necessary
Turn on your radio to see if your fix has improved your signal. If the signal is still poor, you may have a gap in your foil and will need to rewrap the antenna.You may notice that different wrapping techniques have an affect on the clarity of your radio reception. Every antenna break will be different, so you may want to experiment with different ways of wrapping to find the best aluminum wrap for your break.
