What is Discone antenna?
The discone antenna consists of two sections, one shaped like a disk and the other as a cone. The disk is perpendicular to the cone axis and the size of these two folders must fall into a certain ratio for the device to work properly. These antennas are able to receive signals through a wide range of frequencies and from all directions.
The Discone antenna structure allows it to work in a wide part of the electromagnetic spectrum. This type of antenna is omnidirectional, which means that it can receive electromagnetic waves from any direction. It does not need to be directed to the signal source. This antenna is also able to work inside, even if it loses some functionality, because the electromagnetic signal is degraded when the materials of the house or building pass through.
Most Discone antennas are set so that the cone section is down and the disk is at the top. The cone height is equal to a quarter of the smallest frequency that the antenna can pick up, and the disk has a diameter of 0.7 cone lengths. There is an insulator between the cone and the discCorrect function of the antenna. The highest frequency that can be accepted by the antenna Discone is generally about ten times greater than the lowest frequency.
The discone antenna can be solid or can be made of a row of rods. In any case, a conductive metal, such as copper, is an ideal material. If the antenna is made of rods, these rods spread from the bottom of the cone -shaped antenna and in a perpendicular circle on the upper part of the cone. Any number of rods can be used, even if the number is between eight and 16.
The most common use for the Discone antenna is on radio devices such as radio radios and radio scanners that can be used to pick up a remote radiosign. It is possible to transmit the antenna Discone, although the antenna tends to create harmonious signals that can disrupt the quality of transmission. It is not an ideal antenna for use as a transmitter, although a wide range of frequencies it can receive and its schoPosting to receive signals from any direction is ideal as a receiving antenna.
