Below I hooked two 1/2 wave 50 ohm jumpers to two 50 ohm dummy loads. I connected the jumpers to a T-connector and hooked my Autek VA1 to the third port on the T and I saw 28 ohms.
I hooked one jumper direct to the VA1 and got 49 ohms, the other image is also 49 ohms with the VA1 direct into the dummy load.
I don't have a 75 ohm co-phase harness, but if I did and hooked it up in this setup then I would expect the TX'r end of the T-connector to show close to 50 ohms. Am I wrong?
The following is not a transformational harness so we should not see any transformation by the harness, but we do see an approximate halving of the impedance at the transmitter end of the harness.

Sorry for the meter response no showing up well, this meter is old and worn somewhat.
If I'm not wrong, then where are ya'll getting 100 ohms? Is the discussion about a mobile antenna or some other antenna like a quad or maybe a 5/8 wave with an end impedance somewhere around a 100 ohms with a lot of reactance to boot?
NB, you're getting all incredulous again, like I called your momma a bad name. I asked a civil question, and it was not a trick question about the accuracy of the impedance.
BTW, I agree with you not seeing how 4 watts....however you said it.
