Is omnidirectional or directional antenna better?
Is omnidirectional or directional antenna better?
Directional antennas are good for applications that require the available RF energy to be focused in a particular direction. Since their signal is concentrated in a more narrow field than Omni-Directional antennas, they are able to reach out farther to pull in a more powerful signal.
What is an omni directional TV antenna?
In this article we will focus on omnidirectional TV antenna variety. The main difference between the two is that a directional antenna must be pointed in the direction of the TV transmission tower, while an omnidirectional antenna can receive signals equally from all directions.
How far will an omni antenna reach?
Omni-directional antennas work like a lamp. It has a 360 degree coverage area, but has limited range. Under best conditions, it can reach up to 1 mile.
What advantage the omnidirectional antenna has over directional antenna?
The overall gain of the omni antenna is lower, so the peak throughput is lower when generally compared to the directional antenna. An omni antenna is easier to install than a directional antenna and it does not require realignment/adjustment when the network changes (new sites, network problems, etc.).
In which two environments is it best to use omnidirectional antennas?
Due to the fact that omni antennas can transmit and receive signals in any direction, they are commonly used by WISPS with access points. Omnis are ideal for use in rural environments, where initial subscriber counts are expected to be low.
How do I install an omni directional antenna?
Place the antenna in a vertical position. Either right side up or up-side-down is OK. Place the antenna in the middle of the coverage zone and at 1.5m or higher above the floor. Minimize obstructions around the antenna.
