But RADIAN FREQUENCY = 2*PI*f and is denoted by the greek lower case omega.
but thats the ω, I thought that stood for working (V) but also smaller version of Ω **broken link removed**

You mean like this

MUTT77 scope sim taken from
MUTT78 showing cursors measuring XA - XB = DX
X = width, soory Time/period
Y = hieght, sorry (whatever it was showing us)
& was determined in cycles before Hz, no wonder there are so many variations
so in my ariel attachment 1/2 wave simply means half a radian or half wave
Does that mean below or above gnd?
You continually amaze me with your willingness to get into the guts of an instrument and see what it'll do.
Try moving either cursor A or B to a point at the flat peak of the square wave and see if you can get it to read around 8.5VDC.
Yes, the aerial's actual physical length is 1/2 a wavelength (at a specified frequency). Antennae are a whole nother ballgame, believe me. Let's not even go there for the time being.
And the antenna/ground issue is also tied up in wave propagation that is best delayed, for now, in this discussion. Suffice it to say that the length of an antenna (plus its design) AND it's relative physical position above ground (literally, and both tied to a specific frequency), are absolutely critical to optimum transmission and reception parameters. Antenna theory is in a class all by itself.
So you don't want me to ask about a ground plane independant one then
I was going to ask how you determine where the start of the cycle is but this should be able to answer it, when you find '0' degrees, is the start & we can determine how late or early it starts via time
Does that mean it's using the coax as ground?
If you would, please tell us exactly what you did, step by step, to arrive at the posted image. I can't get a clear image in my mind.
OK. If you don't mind, I'm going to recreate the demo and post it later.
As we are up to page 50, are they limited?
Is it worth starting a new thread 'understanding basic electronics 2'
Or is it ok to continue on here?
