2. Optical attenuator - Wikipedia

   en.wikipedia.org/wiki/Optical_attenuator

   Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.

   Bonnie Crystal was granted the US patent 7,151,497 Coaxial Antenna System on December 19, 2006, after filing in 2003 for new types of coaxial antennas with reduced size providing efficient broadband, wideband and controlled bandwidths, using radiation by the outside of the coaxial elements. [2]

4. Attenuator (electronics) - Wikipedia

   en.wikipedia.org/wiki/Attenuator_(electronics)

   Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it. Attenuators are also used ...

5. RG-59 - Wikipedia

   en.wikipedia.org/wiki/RG-59

   RG-59 coaxial cable is commonly packed with consumer equipment, such as VCRs or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because it costs less than RG-6 does. However, given the short lengths provided (usually 4–6 ft or 1.2–1.8 m), this is generally sufficient for its typical use.

6. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   Dipole antennas are bi-directional; that is, they have two main lobes in opposite directions, 180° apart. Instead of being fixed in position like other antennas, the elements are mounted on ball-and-socket joints. They can be adjusted to various angles in a V shape, allowing them to be moved out of the way in crowded quarters.
