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.
A competing third criterion is the number and bandwidth of the frequenc(y/ies) that a single antenna intercepts or emits. A fourth design goal is to make the antenna directional: To project or intercept radio waves from only one vertical and / or horizontal direction as exclusively as possible. Simple antennas
A common subtype is the bowtie antenna, essentially a flattened version of the biconical design which is often used for short-range UHF television reception. These are also sometimes referred to as butterfly antennas. [2] Sir Arthur Lodge is the inventor of the biconical antenna. [3] [4] Omnidirectional biconical antenna
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 .
The tiny design makes them ideal for mobile applications such as wardriving. Cantennas can be used to increase cell phone range, [5] improve reception, and decrease noise. A cantenna can be used as a satellite dish feed horn. The 5.5 GHz cantenna dimensions are almost perfect in that they make a good fit for the standard TV satellite dish.
A growing number of prominent companies have scaled back or set aside the diversity, equity and inclusion initiatives that much of corporate America endorsed following the protests that ...
At the start of November, it had 1,749 stores in 44 states, an 18% increase over a year ago. The company plans to add about 150 new stores in fiscal 2026 (ending early February), which would be ...
The quarter-wave monopole, the most compact resonant antenna, may be the most widely used antenna in the world. The five-eighth wave monopole – length 0.625 λ , or 5 / 8 of a wavelength – is also popular, since at that length monopoles direct the greatest proportion of their radiated power horizontally, hence the best use of ...
