Noise temperature of HyperLog 60100
Hello, I need to know the equivalent noise temperature (Tant) of the antenna HyperLog 60100 because I have to calculate the total noise figure of my receiver using the Friis' formula. I searched that parameter in the datasheet but I didn't find it. Can somebody help me?
Firstly, I read the book "Digital Communications Fundamentals And Applications" written by Bernard Sklar and I realized that the antenna's noise temperature (Tant) depends on the place where it is and the direction that it is pointing. So the antenna temperature is a measure of the noise introduced by the antenna taking into account its antenna pattern.
Secondly, I found in the same book that the receiver's composite noise figure (or total noise figure as I called it) is calculated from the antenna terminals to the last element of the front end. So it isn't necessary to know the antenna temperature to calculate that parameter.
Have I understood these concepts fine?
