2. Gain (antenna) - Wikipedia

   en.wikipedia.org/wiki/Gain_(antenna)

   In electromagnetics, an antenna's gain is a key performance parameter which combines the antenna's directivity and radiation efficiency. The term power gain has been deprecated by IEEE. [1] In a transmitting antenna, the gain describes how well the antenna converts input power into radio waves headed in a specified direction. In a receiving ...

3. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...

4. Antenna measurement - Wikipedia

   en.wikipedia.org/wiki/Antenna_measurement

   An antenna designer must take into account the application for the antenna when determining the gain. High-gain antennas have the advantage of longer range and better signal quality, but must be aimed carefully in a particular direction. Low-gain antennas have shorter range, but the orientation of the antenna is inconsequential.

5. Radiation pattern - Wikipedia

   en.wikipedia.org/wiki/Radiation_pattern

   The second antenna is a reference antenna, which points rigidly at the first antenna. Each antenna is alternately connected to a transmitter having a particular source impedance, and a receiver having the same input impedance (the impedance may differ between the two antennas).

6. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   A directive antenna with moderate gain of about 8 dBi often used at UHF frequencies. Consists of a dipole mounted in front of two reflective metal screens joined at an angle, usually 90°. Used as a rooftop UHF television antenna and for point-to-point data links. Parabolic The most widely used high gain antenna at microwave frequencies and above.

7. The 7 Best HDTV Antenna Amplifiers of 2023 For a Better Signal

   The Cimple TV Antenna Amplifier is a powerful distribution amplifier with an adjustable gain feature that reaches up to 24 decibels. Simply turn the adjustment knob to the amount of gain needed ...

8. Log-periodic antenna - Wikipedia

   en.wikipedia.org/wiki/Log-periodic_antenna

   An antenna array consisting of two such antennas, one above the other and driven in phase has a gain of up to 17 dBi. Being log-periodic, the antenna's main characteristics ( radiation pattern , gain, driving point impedance ) are almost constant over its entire frequency range, with the match to a 300 Ω feed line achieving a standing wave ...

9. Antenna (radio) - Wikipedia

   en.wikipedia.org/wiki/Antenna_(radio)

   High-gain antennas have the advantage of longer range and better signal quality, but must be aimed carefully at the other antenna. An example of a high-gain antenna is a parabolic dish such as a satellite television antenna. Low-gain antennas have shorter range, but the orientation of the antenna is relatively unimportant.
