2. Gonset Communicator - Wikipedia

   en.wikipedia.org/wiki/Gonset_Communicator

   The Gonset Communicators were packaged in a square box with a carrying handle and a UHF connector for the antenna on top, making them quite portable. Early models had a magic eye tube tuning indicator in front. The configuration earned them the name "Gooney Box." The radios could operate from 110 volt AC mains, or 6 or 12 volt DC from a car ...

   Adjacent frequencies are often used by illegal operators using modified CB or amateur radio equipment. Operators sometimes refer to this activity as freebanding. The Industrial/Business Radio Pool of the Private Land Mobile Radio Services has several channels just above the Citizen's Band, at 27.430, 27.450, 27.470, 27.490, 27.510, and 27.530 MHz.

4. Antenna rotator - Wikipedia

   en.wikipedia.org/wiki/Antenna_rotator

   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 ...

   This antenna radiates maximally in directions perpendicular to the antenna's axis, giving it a small directive gain of 2.15 dBi (2.15 dBi means that in the direction of maximum radiation, signal strength is 1.64× the signal from a directionless "isotropic" antenna). Doublet "Doublet" is a name radio amateurs sometimes use for a dipole antenna ...

7. RG-58 - Wikipedia

   en.wikipedia.org/wiki/RG-58

   RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System.
