Return loss
The ratio of reflected power to inserted power. Return loss is a measure of the signal reflections occurring along a channel or basic link and is related to various electrical mismatches along the cabling. This ratio, expressed in decibels, describes the ratio of optical power reflected by a component, for instance a connector, to the optical power introduced to that component.

RG59

RG59-Registered number 59 is a coaxial type cable.
It is suitable for basic analogue TV antenna feeds in residential applications and for basic CCTV systems over short cable runs.


Tip: RG59 is a similar size to RG62 and so connectors/ boots for the RG59 will fit RG62.
