Very Low Power

I am experimenting with power in the 1,2 & 5 milliwatt range. From my QTH in Connecticut I am heard in a few countries on Europe with 5 milliwatts, England & Spain with 2 milliwatts, and Spain alone with 1 milliwatt. At these low powers I am wondering how much of the power is being radiated from the antenna itself compared to the power being radiated from coax leakage, antenna tuner leakage, attenuator leakage, and even from the transmitter itself. I am going to put a dummy load in place of the antenna and repeat the experiment and see if my signal is still heard. Does anyone out there have any experience/knowledge on this topic?
