What is an antenna of saliva®?
Slinky® antenna is an antenna made with a baby toy known as saliva. Slinkies® are spiral metal coils that, when used as toys, show interesting properties such as the ability to "walk" up the stairs and across flat surfaces. They can also be very useful for home antenna projects depending on how the antenna is used. Many toy stores carry Slinkies® and similar products created by other companies, often at very low costs, which makes them cheaper than some conventional antenna supplies. The spiral antenna can be adjusted to change the way it resonates, by changing the number of curves or their amount of extension. It is important to realize that with the saliva antenna® the metal has not been protected by anti -corrosive materials, so it may not be suitable for outdoor use.
The classic use of the saliva® is in the dipole antenna, with two slings® extended in opposite directions and connected to the center element. Slinkies® length can be adjusted to resonate atdifferent frequencies and provided multiple tuner resources in the middle. This extends the range of frequencies that can be picked up and provides people with many different options to tune in.
The advantage for the use of saliva® as an antenna, above low costs, which is accessible amateur radio operators, is portability. Slinkies® can be compressed if they are not used to create a compact coil that can be easily transmitted in the radio set. Slinky® antenna can also be stored if it is not used, for people working in settings, such as homes, where antenna fields may not be desirable to be used when the radio is not used.
When expanded, Slinkies® should be supported by a cable or wire length. The coils are not strong enough to support the widespread weight and the antenna otherwise drops and deforms differently. It is also important to avoid pulling the antenna Slinky® too far, otherwise the helix canlose your naturally spring properties. Slinkies® can also become prone to tangling when they are often extended and left back in the spring. When the devices get entangled, they should be gently uninvited from one end to the other and have not been forced or may be distorted.
