Rg-59
|
A type of coaxial cable that is most common in use in small to medium size cctv systems. it is designed with an impedance of 75 ohms. it has an outer diameter of around 6 mm and it is a good compromise between maximum distances achievable (up to 300 m for

Compromise, английский
The mutual agreement of a party or parties at difference, to refer to arbitration, or make an end of the matter.

Rms, английский
- An abbreviation for root mean square. all ac voltages are measured with multimeters that show the rms value of the signal (not the peaks). for a sine wave signal such as the mains, the rms value happens to be 1.41 times (square root of 2) below the peak v
- Root mean square.this notation is used frequently with error analysis. in that context, it is the square root of the arithmetic mean of the squares of the deviations of the individual calibration points from the theoretical or ideal response.
- The "effective" values of measured ac voltage or amperage. rms equals 0.707 times the maximum, or peak value.

- Abbr. for “root mean square.”
- Royal mail ship. starting in 1840, british overseas mail was carried in vessels operated by the admiralty, but titled rms rather than hms. later, private liners were contracted to perform this duty and for them and their passengers the rms designation became a mark of prestige with implications of speed and timely arrival. see titanic mailmen.

Rg-58, английский
A coaxial cable designed with 50 ohms impedance, therefore not suitable for cctv. very similar to rg-59, only slightly thinner.
