  • Coaxial cable
  • Radial cable
  • A pair of sharp scissors
  • A measuring tape
  • A Soldering gun

The Steps to Build Your Own UHF VHF TV Antenna

Step 1. Coaxial Cable

Let us first start with the coaxial cable. Take the coaxial cable and measure up to 21 or 22 inches of the coaxial cable and make a mark of it.

Step 2. Outer Insulation

Next, remove around 21 or 22 inches of the outer insulation portion of the coaxial cable measured above.

Step 3. Soldering

Also, make sure to remove the shield of the wire from one side of the inner coaxial cable. Always be cautious to not cut into the coaxial cable or else you will have to begin all over again from scratch. Aim to leave 21 or 22 inches of the cable exposed. Also, make sure to leave an inch for soldering the three radials to it. (2)

Step 4. Radial Cable

Solder the radial cable to the coaxial cable’s shield on the end that has been cut with the help of a solder gun. Ensure the cables are long enough to be soldered to the shield.

Step 5. Single Radial Cable

 Next, solder the two remaining coaxial cables to the single radial cable.

Step 6. Spread out Cables
