2. Omnidirectional antenna - Wikipedia

   en.wikipedia.org/wiki/Omnidirectional_antenna

   Whip antenna on a walkie-talkie. In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis ( azimuthal directions), with power varying with angle to the axis ( elevation angle ), declining to zero on the axis. [1] [2] When graphed in three dimensions (see ...

3. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   In radio systems, many different antenna types are used whose properties are especially crafted for particular applications. Most often, the greatest effect is due to the size of the radio waves the antenna is to intercept or produce; one competing second effect is differences in optimization for receiving and for transmitting; another competing influence is the number and bandwidth of the ...

4. Sector antenna - Wikipedia

   en.wikipedia.org/wiki/Sector_antenna

   Typical GSM sector antenna outdoor unit. A sector antenna is a type of directional microwave antenna with a sector-shaped radiation pattern.The word "sector" is used in the geometric sense; some portion of the circumference of a circle measured in degrees of arc. 60°, 90° and 120° designs are typical, often with a few degrees 'extra' to ensure overlap and mounted in multiples when wider or ...

5. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   Whip antenna on car. A whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna. The antenna is designed to be flexible so that it does not break easily, and the name is derived from the whip -like motion ...

6. Distributed antenna system - Wikipedia

   en.wikipedia.org/wiki/Distributed_antenna_system

   A distributed antenna system ( DAS) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level, and node installations are compact.

7. Long-range Wi-Fi - Wikipedia

   en.wikipedia.org/wiki/Long-range_Wi-Fi

   Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access . Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [1]
