2. Eco-Drive - Wikipedia

   en.wikipedia.org/wiki/Eco-Drive

   [9] [10] [11] The Concept Model 2011 was the Eco-Drive SATELLITE WAVE that has a movement that can receive time synchronization signals from GPS satellites. This makes radio-controlled timing possible in remote areas that are not serviced by land based radio time signal stations. [12] In 2012 Citizen announced the Eco-Drive RING Concept Model.

3. Satellite dish - Wikipedia

   en.wikipedia.org/wiki/Satellite_dish

   A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit .

4. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   A 'whip' antenna at the side of a Casio portable TV. Some portable televisions use a whip antenna. [6] This consists of a single telescoping rod about a meter (3.3 feet) long attached to the television, which can be retracted when not in use. It functions as a quarter-wave monopole antenna.

5. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   Traveling wave antennas Traveling wave antennas are notably one of the few types of antennas that are normally not self resonant: Electrical waves induced by received radio waves travel through the antenna wire in the direction that the arriving RF signals are travelling. Only electrical waves traveling toward the feedpoint are collected; waves ...

6. Turnstile antenna - Wikipedia

   en.wikipedia.org/wiki/Turnstile_antenna

   A common shape today is the batwing or superturnstile antenna, used for television broadcasting in the VHF or UHF bands [8] The batwing shape of each element produces an antenna with wide impedance bandwidth. [1] Up to eight batwing antennas are usually stacked vertically and fed in phase to make a high gain omnidirectional antenna for TV ...

7. Beam waveguide antenna - Wikipedia

   en.wikipedia.org/wiki/Beam_waveguide_antenna

   The first full scale beam waveguide antenna was the 64 meter antenna at the Usuda Deep Space Center, Japan, built in 1984 by the Japan Aerospace Exploration Agency. [6] After the Jet Propulsion Lab (JPL) tested this antenna and found it better than their conventional 64-meter antennas, [ 7 ] they too switched to this method of construction for ...
