What exactly txsite.SystemLoss stands for?

I'm not sure what does the property of SystemLoss of txsite object stand for? The definition says "it's a nonnegative scalar in dB, and includes transmission line loss and any other miscellaneous system losses". (1) So does this mean it only represents loss but not gain? Say if the txsite in my case was a Standard Gain Horn, which gain is 10 dB, how to describe the gain? (2) Is the system loss from txsite internal or external, e.g. from the upstream devices as S21? Thanks in advance.

Hi Huang,
As per my understanding, you want to know more about the “SystemLoss” property of “txsite” object, if it represents gain and is the loss external or internal.
The “SystemLoss” property of a "txsite" object in MATLAB represents loss within the system that is not accounted for by the other properties of "txsite". This loss is typically a combination of transmission line losses (due to cables, connectors, etc.) and any other miscellaneous losses.
“SystemLoss” property is specifically designed to represent losses in the transmission system, and it should be a nonnegative scalar in decibels.
The “txsite” object in MATLAB is a representation of a transmitting site in a wireless communication system. It is used to model the characteristics and properties of the transmitting site, such as its location, antenna properties, and system losses.
If the antenna is a horn, it’s properties can be configured in the “Antenna” property of “txsite”.
The “SystemLoss” property is meant to represent internal losses within the transmitter system itself, not losses from upstream devices or losses that occur after the signal has left the antenna (such as path loss through the environment)
Please refer to the following documentation for more information about horn-antennas:
Hope this helps!
