2. Bonding jumper - Wikipedia

   en.wikipedia.org/wiki/Bonding_jumper

   This is done for electrical safety grounding, static electricity protection, and may also be useful for control of electromagnetic interference. For example, a control panel door may have a bonding jumper across the hinges so that the metal door is effectively connected to ground, since the hinges may not provide a reliable contact.

3. RG-59 - Wikipedia

   en.wikipedia.org/wiki/RG-59

   RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms, and a capacitance of around 20pF/ft (60pF/m). [1]

4. Counterpoise (ground system) - Wikipedia

   en.wikipedia.org/wiki/Counterpoise_(ground_system)

   It consists of a network of radial copper wires suspended above the ground, connected to the transmitter feedline ground. It is suspended about 8 feet above ground, so technicians can get access to the helix house at the foot of the tower. Antenna used in Lodge-Muirhead wireless system around 1900, the first counterpoise.

5. Shielded cable - Wikipedia

   en.wikipedia.org/wiki/Shielded_cable

   The best way to wire shielded cables for screening is to ground the shield at both ends of the cable. [6] Traditionally there existed a rule of thumb to ground only the source end of the shield to avoid ground loops. Best practice is to ground at both ends, but there is a possibility of ground loops.

6. Ribbon cable - Wikipedia

   en.wikipedia.org/wiki/Ribbon_cable

   Sometimes a larger width is used & stripped back to what is needed e.g. a 26way IDC cable can have one wire easily removed to give a 25way (before adding the connectors). The wire is usually stranded copper wire, usually either 0.32, 0.20, or 0.13 mm 2 (22, 24, or 26 AWG). Finer and coarser pitch cables are also available.

7. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   To reduce this loss these antennas often use a conductive copper ground screen under the antenna connected to the buried ground wires, either lying on the ground or elevated a few feet, to shield the ground from the electric field. In a few cases where rocky or sandy soil has too high a resistance for a buried ground, a counterpoise is used. [11]
