2. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

3. Beverage antenna - Wikipedia

   en.wikipedia.org/wiki/Beverage_antenna

   The AT&T receiving Beverage antenna (left) and radio receiver (right) at Houlton, Maine, used for transatlantic telephone calls, from a 1920s magazine. The Beverage antenna or "wave antenna" is a long-wire receiving antenna mainly used in the low frequency and medium frequency radio bands, invented by Harold H. Beverage in 1921. [1]

4. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   Indoor antennas are designed to be located on top of or next to the television set, but are ideally placed near a window in a room and as high up as possible for the best reception. [1] The most common types of indoor antennas are the dipole [2] ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. [3]

5. Cellular repeater - Wikipedia

   en.wikipedia.org/wiki/Cellular_repeater

   A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.

6. Directional antenna - Wikipedia

   en.wikipedia.org/wiki/Directional_antenna

   Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.

7. Ultima Online expansions - Wikipedia

   en.wikipedia.org/wiki/Ultima_Online_expansions

   Ultima Online: High Seas is the first and only booster pack for the game. High Seas was announced during a UO Town Hall Meeting held on August 28, 2010 at EA Mythic/Bioware's division headquarters in Fairfax, Virginia. It was introduced with the title Adventures on the High Seas but later trimmed to just High Seas. It was announced that the ...

8. Antenna diversity - Wikipedia

   en.wikipedia.org/wiki/Antenna_diversity

   The base station will switch reception to one of two antennas depending on which is currently receiving a stronger signal. For best results, the antennas are usually placed one wavelength apart. For microwave bands, where the wavelengths are under 100 cm, this can often be done with two antennas attached to the same hardware. For lower ...

9. Biconical antenna - Wikipedia

   en.wikipedia.org/wiki/Biconical_antenna

   A truncated biconical antenna showing the typical "mace head" shape. In radio systems, a biconical antenna is a broad-bandwidth antenna made of two roughly conical conductive objects, nearly touching at their points. [1] Biconical antennas are broadband dipole antennas, typically exhibiting a bandwidth of three octaves or more.
