In pathloss calculation, have I to include the antenna gains with S21 value?

Recently I have used N9925A for S21 measurement, in a wave propagation study experiment. I have used the standard test antenna supplied with VNA as Tx antenna and my own antenna for reception. In pathloss calculation, have I to include the antenna gains? If yes, how? 

In VNA the output power is -15dBm. Does it have any impact in s21 measurement?
