Feb 27, 2020 · You've heard it's possible to build your own HDTV antenna to receive digital terrestrial (DVB-T) signals. It sounds like a good idea, and a big saving. You're planning on cutting the cord, and this sounds ideal. But is it possible? Yes, it is! Here are six ways you can build your own HDTV antenna using household items.

Dec 22, 2023 · Using a HDTV (High-Definition Television) antenna, based on the DB4 design, is 1 of the most effective ways to retrieve HDTV signals. Purchasing this type of antenna at a store will cost you at least $40. However, you can build such an antenna yourself at a much lower cost.

- Find Your Local Transmission Tower. Knowing where the nearest TV transmitter is will help you to correctly align your antenna. You have different options for this.
- Preparing the Wooden Base. Begin by preparing the wooden backing board: Draw a 1-inch gap down the middle. Starting 2 inches from the top, mark a line crossing that gap every 5.25 inches.
- Cut the Coat Hangers. Next, cut eight lengths from the coat hangers, each 14 inches long. Each wire length must be bent halfway, to create a V shape, the ends which must be three inches apart.
- Attach the V Wires to the Base. Next, drill eight guide holes for attaching the V wires, using a narrow bit. With the holes drilled, attach the V wires, using the screws and the washers.
- Choose the rod length for your antenna. You will need 2 rods that are 46.4 inches (117.8 cm) long if you are designing the antenna to listen to non-commercial radio stations such as college channels.
- Place your rods perpendicular to each other and tie them together with a piece of string or tape. You might need to tape together extra pieces to brace the frame.
- Wrap insulated wire around 3 of the frame edges in the formation of a square. These lengths will be of equal size. You will need 32.8 inches (83.2 cm) of wire for the non-commercial type of antenna's 3 sides.
- Tie together the corners of the last side with tape to pull the wire taunt. This 4th side is comprised of 2 half lengths coming together to form the final side.
You can run coaxial cable from the antenna to a TV (or two, with a splitter) and watch live HD television. You can get TV on your computer or laptop with a USB tuner. Or you can set up your home network to watch TV on nearly any device, with a network tuner like the HDHomeRun.

To make an omnidirectional TV antenna, you will need a few materials such as PVC pipes, measuring tape, and coaxial cable. First, assemble the front and back pieces of PVC, then attach the handle piece and the director and reflector elements. Solder the driven elements and secure the coax cable. Finally, test the antenna outside.
