The discone antenna has a useful frequency range of at least 10 to 1. [2] [3] When employed as a transmitting antenna, a properly constructed discone is just as efficient as an antenna designed for a more limited frequency range. The extra bandwidth comes from the controlled taper and large termination radius of the cone.
It is the only type of directional antenna that is directional ("beam" antenna) over its entire working range. discone antenna The discone is omnidirectional, vertically polarized, and has a gain similar to a dipole. It is equally efficient as a monopole and is exceptionally wideband, offering a frequency range ratio of up to approximately 10:1 .
Although the name is similar to the folded unipole, the two antennas are electrically different: The folded monopole is a much simpler antenna. Discone antenna The discone is a monopole version of a biconical antenna. The name of the antenna describes its shape: A metal disk above a metal cone.
A truncated biconical antenna showing the typical "mace head" shape. In radio systems, a biconical antenna is a broad-bandwidth antenna made of two roughly conical conductive objects, nearly touching at their points. [1] Biconical antennas are broadband dipole antennas, typically exhibiting a bandwidth of three octaves or more.

Mexican authorities said they recovered a total of 31 bodies from pits in a southeastern state plagued by cartel violence since they began excavating the improvised graves at the weekend.
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
New York’s new toll for drivers entering the center of Manhattan debuted Sunday, meaning many people will pay $9 to access the busiest part of the Big Apple during peak hours.
