What effect does high voltage have on capacitance and how to measure it?
How much do the capacitors have to change to cause a +/- 10 Hz shift in resonance?
Can a number 2 pencil be used to lower a crystal's resonance?
Thanks for everyone's comments.

It was mentioned that The Signal Path channel made a video on 3D printed waveguides. The attached link takes you to what I believe they were referring to. He made a few horns and a filter. He's experimenting at much higher frequencies than I am and surface finish.

During this video, I show a couple of printed horns from the following link. Maybe we can test them out in the future.

Jiri Bekr,
"UT61E+ is the only multimeter with classic shunt wire, that even when overheated, still has the same reading, no matter the shunt temp. I have overloaded the multimeter (1 minute at nominal current should be enough for CUT indication), and the measurement was still absolutely correct (after the CUT was done beeping). Any other multimeters begin showing more and more, until you get like 12A on display while just 10A is passing through the multimeter. Usually shunt wire gets hot at nominal current, begins to expand its length and increases resistance, so also increasing burden voltage, causing bad reading. Some SMD shunts are prone to this too, but not that significantly of course."

The BALUN uses a Mini-Circuits TC1-1-13M. The paper shows a start frequency of 1MHz where this transformer is spec'ed for 4.5M - 3G. Digikey still offers an evaluation board for this transformer (shown in previous picture). Datasheet may be found here:

Datasheet for the ADT2-1T may be found here:

While the TC1_1_13MA was setup as a current BALUN, the ADT2-1T was setup as a voltage BALUN. Attached showing the return loss of the four pairs on our 1Gb Ethernet after calibration.
