"""metal is required. Plastic has no effect on the signal,"""
not entirely true ! I did a background add on class in college in "Microwave magic " as I call it ..
We used acrilc lenses to slightly bend and refract the beam from our Ku band Gunn sorces and then did a power plot of the power VS angle .
There was a significant difference in the lens vs no lens plots
Microwave safe containers are Great example of RF interaction in plastics .
So are Radomes used in NOAA Doppler stations .
Propagation volicy in coax is also a example of RF and dialectics constant and RF interaction Via plastics..
Mind .. it Is near to impossible to make a waveguide from PTFE ,
But you can most denfetlay refract uWave energy with certain plastics ..

PJ Allen, as others have noted, I have to agree that your “mostly content-free posts” and mocking those who could have benefited from your self acclaimed expertise serve only to flatter yourself.
And Peter, having a college education (as you state), why can’t you spell simple words like acrylic, velocity, and definitely in a very short set of remarks?
Given this, do you guys really expect us to take you seriously in the future?

NOT! Or is this what we call “change”?
