Case i: Consider the effect of inserting a lossy waveguide (cable) between the antenna & the LNA

The overall system noise temperature referred to the input,

$T_{s}=T_{ant}+T_{e1}+\frac{(L-1)T_0}{G1}+\frac{L(F-1)T_0}{G1}$

L represents the power loss of the cable.

The power loss is simply the ratio of input power to output power and is …
