The most effective TV antenna made in rural areas

You can make a simple TV antenna with cans and wires.

6 cans, 1 thin copper tube (or 8 steel wires) with a length of 90cm, and 5 insulating strips. Connect and fix five insulating strips with cap screws to make a bracket as shown in the figure (the long side of the strip frame is 42 cm, the wide side is 12 cm, and the hypotenuse is 20 cm).

Three groups of tanks are symmetrically and parallelly fixed on the bracket with cap screws. The spacing between AB, CD and EF (referring to cans) is10cm; The spacing between AC, CE, BD and DF is 20 cm. From GH to the midpoint of CE and DF (i.e. 10 cm), the copper wire is bent into a ring with a diameter of 25 cm and fixed in GH with a cap screw, and the copper wire ring is vertical to the bracket.

Can the old TV antenna still be used now?

You can answer it now, but it's best to do it indoors, because our city is developing rapidly now, especially high-rise buildings, which will shield and weaken these signals.

Antenna is a kind of transducer, which converts guided waves propagating on transmission lines into electromagnetic waves propagating in unbounded media (usually free space), and vice versa.

The part of radio equipment used to transmit or receive electromagnetic waves. Radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems. Anyone who uses electromagnetic waves to transmit information works by antennas.
