Would you like to access multiple TV channels without having to pay expensive subscriptions?
This project will allow you to build a homemade antenna using common elements, such as coaxial cable and a splitter.
We recommend: Do you need to connect your cell phone to your TV? Follow this quick and easy step-by-step guide
By following these steps, you will be able to enjoy a stable and good quality signal, ideal if you are 10-15 km from a transmitting antenna.

- Procedure
Necessary materials
RG6 type coaxial cable: 2 sections (one of 75 cm and the other of 61.5 cm).
Splitter: Available in hardware or electronics stores.
F-type connectors: 2 units.
Cutter, pliers or scissors.
Clamp.
Hot silicone (optional).
Procedure
Cable preparation :
Cut two lengths of coaxial cable: one 75 cm long and one 61.5 cm long .
On the 75cm cable, measure 4.5cm from one end and mark. Then, remove the outer insulation and clear the braid, taking care not to damage the centre conductor. Do the same with the opposite end, but removing only 1.2cm to accommodate the F-type connector.
75cm cable connection :
Place the F-type connector on the prepared end. Make sure that the shield does not touch the center conductor, as this will cause a short circuit.
Preparing the 61.5 cm cable :
Mark 7.2 cm from one end and remove the insulation, following the same procedure as for the 75 cm cable. Repeat on the opposite end with a 1.2 cm mark for the F-type connector.
Formation of dipoles :
Bend the end of the center conductor at 90 degrees and use a circular object (diameter 7-10 cm) to roll it into a ring. Make sure the circle is perfect.
At the other end, insert the tip of the conductor between the mesh and the outer insulator, taking care not to touch the center conductor.
Final assembly :
Connect both cables to the splitter and place the antenna near a window or outside. To protect it from moisture, apply hot silicone to the connections.
Settings and location :
If you want to improve reception, add a reflector about 17 cm from the antenna. This step is optional, but can increase signal stability.
Tips for a better result
Avoid stormy days : Disconnect the antenna to prevent damage from atmospheric discharges.
Try different positions : Placing the antenna in high places or near windows improves reception.
Take care of the connections : Check that no filament of the mesh touches the central conductor.
With this method, you will get a functional and economical antenna to enjoy digital television.
