Omni Antennas

Omni Antennas Manufacturer

C&T RF Antennas Inc is an indoor-outdoor Omni antennas manufacturer, omnidirectional antennas supplier in China.

What is an Omni antenna?

In radio communication, an omnidirectional antenna is a class of antenna that radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with an angle to the axis (elevation angle), declining to zero on the axis.

What is meant by Omni antenna?

Omni/Omnidirectional antennas receive signals equally from all directions. Directional antennas pull in signals better from one direction. In this direction, they can detect a weaker or more distant signal than an equivalent omnidirectional antenna.

What are the characteristics of an omnidirectional antenna?

An omnidirectional antenna radiates radio wave power uniformly in all directions in one plane, with the radiated power decreasing against elevation angles above or below the plane, dropping to zero on the antenna’s axis, and producing “doughnut-shaped” radiation.

What are Omni antennas used for?

Omni/Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, etc.

What are Omni antenna types?

Common types of low-gain omnidirectional antennas are the whip antenna, “Rubber Ducky” antenna, ground plane antenna, a vertically oriented dipole antenna, discone antenna, mast radiator, horizontal loop antenna (sometimes known colloquially as a ‘circular aerial’ because of the shape) and the halo antenna.

When should an Omni antenna be used?

Omni antennas are best suited for situations where you need to support multiple cell phone carriers, each with their own cell tower, and are already receiving at least three bars of signal outside of your building or vehicle.

Is a whip antenna omnidirectional?

The whip antenna is a monopole antenna, and like a vertical dipole has an omnidirectional radiation pattern, radiating equal radio power in all azimuthal directions (perpendicular to the antenna’s axis), with the radiated power falling off with elevation angle to zero on the antenna’s axis.

Is parabolic antenna omnidirectional?

– Omni-directional antennas propagate in all directions.

– semi-directional antennas propagate in a constricted fashion, defined by a specific angle.

– Directional antennas have a narrow “beam” that allows highly directional propagation; familiar types are the parabolic and Yagi.

Which is better Omni or directional antenna?

Both the omnidirectional antennas and directional antennas can be useful depending on your situation. The bottom line is that directional antennas are more powerful, however, can be less convenient than omnidirectional antennas in certain situations because they only point in one direction.
