2. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   The resistance of copper wire is approximately ⁠ 1 ohms / 1000 feet ⁠ for 10 AWG, ⁠ 10 ohms / 1000 feet ⁠ for 20 AWG, ⁠ 100 ohms / 1000 feet ⁠ for 30 AWG, and so on. [ 5 ] : 27 Because aluminum wire has a conductivity of approximately 61% of copper, an aluminum wire has nearly the same resistance as a 2 size thinner copper wire ...

3. Twin-lead - Wikipedia

   en.wikipedia.org/wiki/Twin-lead

   Twin lead cable is a two-conductor flat cable used as a balanced transmission line to carry radio frequency (RF) signals. It is constructed of two, stranded copper wires, or solid copper-clad steel wires. The wires are held a fixed distance apart by a plastic ribbon that is a good insulator at radio frequencies (usually polyethylene).

4. 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] The 75 ohm impedance matches a dipole antenna in free space. RG (for radio guide) was originally a unit indicator for bulk radio frequency ...

5. RG-6 - Wikipedia

   120 fathoms. 720 ft. Metric (SI) units. 219.5 m. A cable length or length of cable is a nautical unit of measure equal to one tenth of a nautical mile or approximately 100 fathoms. Owing to anachronisms and varying techniques of measurement, a cable length can be anywhere from 169 to 220 metres (185 to 241 yd), depending on the standard used.
