A broke analog clock is right twice a day.
For it to be right, you just have to know "when" to read it.

If you could insert that same SWR meter at various lengths along your  
transmission line you might see 200 watts or ZERO watts reflected.

Did your amplifier load or tune change due to this different reading ?  No.

Did your amplifier change power output due to this different reading ?  No.

So what does your swr meter "really" measure ?

We know it measures "something".......... BUT WHAT ???



Power ( watts ) = voltage x current
( or does that apply  in a transmission line ? Hummmmmmmmm   )
