A couple of questions about your data. What kind of coax and
connectors are used for the BVT?
hardline of RG-58 dimension;
only two connectors, the gozinta, and the comesoutta (never changed
throughout any variation nor calibration).
What kind of wattmeter was
used for the readings?
Bird.
The load seems to be 50/3 = 16.67 ohms. I would like to see
the same data for a load of 50 ohms.
That is already discussed in the report.
Seems you are getting
the same resulting effect that I do (on purpose) when I vary
the length of my ladder-line while watching the 50 ohm SWR.
Your results may repeat every 1/2WL. What if you had gone
out to 20 feet instead of stopping at 15 feet?
I have no reason to think it would offer any change in a periodic
variation already in evidence.
One last thought. Did you consider common-mode current
possibilities?
Yes.
