It does really not exist per say. It is just an envelope modulation on the carrier related to group delay, medium velo; /archives//html/Towertalk/2001-12/msg00281.html (10,820 bytes)

SWR is a simple ratio. SWR is not a wave. SWR, being unitless, cannot possibly "carry energy". SWR is not a SYMBOL for the mismatch ratio b; /archives//html/Towertalk/2001-12/msg00283.html (8,470 bytes)

So you will see my point. SWR is for RF what INFLEXION is for voice. Not quite but enough to make the point. Comprende Pa; /archives//html/Towertalk/2001-12/msg00286.html (10,657 bytes)
