What is the difference between omni directional and directional antennas?

∙ 15y ago
An omni directional antenne receives or transmits signals from all directions as in 360 degrees. A directional antenne is aimed in a specific direction so that it may direct an outgoing signal to or receive a signal from a specific source.

What type of antenna using in mobil bug?
omni directional antennas
Which WiFi router is best in a building?
a MIMO router with omni-directional antennas, perhaps with higher gain than stock antennas.
What is the difference between Omni-directional and Unidirectional Microphones?
Omni-directional microphones are meant to pick up sound from any direction at any time. Unidirectional microphones pick up sound from only one direction.
Why have two antennae on a wireless router?
It increases signal strength and range in all directions while using omni-directional antennas.
What are the disadvantages of omni directional wheel?
diameter is high
What is the directional properties of antenna?
omni-directional is the opposite of directional. A directional antenna receives or sends more signal from or to the front than the sides or back.

Can you use a TV antenna for a remote control helicopter antenna?
If the TV antenna was built for the correct frequency, it would work but my second thought is do you want the antenna to send a directional signal? I would think a "omni" signal (all direction pattern) would be a better choice. Most TV antennas are directional.
Are 3D sound cards bidirectional?
No. 3D soundcards are omni directional
Advantages of omni directional antenna?
can transmit in all directions with a donut shaped radiation pattern.
What is cell sectoring?
In cellular telephone system, co-channel interference can be decreased by replacing a single omni directional antenna with several directional antennas, each radiating within a smaller area.In sectoring,we keep unchanged cell radius & seek methods to decrease D/R ratio.By D/R ratio,SIR increase so we use directional antennas.remember D/R is co-channel reuse ratio & SIR is signal to interference ratio
Why aircraft vhf antennas are polatised vertically?
Aircraft can approach an antenna from any direction, so antennas need to be omni ("all") directional in the horizontal plane. Early on, the easiest way to get omnidirectionality was to use vertical polarisation, and it's also the simplest kind of antenna - a simple rod or wire (of the right length) works just fine. Subsequent antenna design has produced omnidirectional antennas with horizontal polarisation, but there are no significant advantages, and the design/construction is more complex than a vertical equivalent.
