WebMy specs also require measuring the VSWR of the output ports of the amplifier. I have been a bit confused as to how the network analyzer can measure this properly. My understanding is that an S11 vs an S22 is that the analyzer source swaps the source to each port. ... So, typically a measurement result of its input VSWR is an assumption that ... Webmatched to the feedline. VSWR can be calculated from the reflection coefficient by the following: VSWR = (1+p)/(1-p) Using this formula shows your VSWR at the antenna is 3:1, quite a different value than your VSWR meter reads. The difference in the input and output VSWR values is due to the loss introduced by the feedline.
