The Ground-Based Operational Surveillance System, (G-BOSS) created by Raytheon Integrated Defense Systems, is a trailer-mounted tower with mounted surveillance systems.It was integrated with the command operations center (COC) used primarily by the United States Marine Corps during the War in Afghanistan (2001-2021) and the War in Iraq.
An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...
New Boston Space Force Station (BOSS) is a United States Space Force facility located in Hillsborough County in south central New Hampshire. It was transferred from the United States Air Force to the Space Force in the summer of 2020. [1] The installation occupies more than 2,800 acres (11 km 2) in three towns: New Boston, Amherst, and Mont Vernon.
Typical center-loaded mobile CB antenna. Note the loading coil, which shortens the antenna's overall length. 27 MHz is a relatively long wavelength for mobile communications, and the choice of antenna has a considerable impact on the performance of a CB radio. A common mobile antenna is a quarter-wave vertical whip.
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.
An inverted vee antenna is a type of antenna similar to a horizontal dipole, but with the two sides bent down towards the ground, typically creating a 120- or 90-degree angle between the dipole legs. It is typically used in areas of limited space as it can significantly reduce the ground foot print of the antenna without significantly impacting ...
The Adcock antenna array uses a pair of monopole or dipole antennas that takes the vector difference of the received signal at each antenna so that there is only one output from each pair of antennas. Two of these pairs are co-located but perpendicularly oriented to produce what can be referred to as the N–S (North-South) and E–W (East-West ...
Often random wire antennas are also (inaccurately) referred to as long-wire antennas.There is no accepted minimum size, but actual long-wire antennas must be greater than at least a quarter-wavelength ( 1 / 4 λ) or perhaps greater than a half ( 1 / 2 λ) at the frequency the long wire antenna is used for, and even a half-wave may only be considered "long-ish" rather than "truly ...
