what is your vswr at the antenna?

The first meter will add to the reading of the second meter. Every connection you make creates loss. How much depends on the meter movement and internals. You read at one end or the other.
 
Well let's see.I currently have 10 antennas up for my base setup & all except one are under 1.5.1 & the exception in my G5RV which varies depending upon which band I am on & I only use that antenna for 40,60,75 meters.SWR has never been an issue for base or mobile antennas for me & I never understood why so many people have so many issues with their SWR?

Thread's just a bit over 4 years old...
 
Let's go back to some basics. VSWR is a measurement based on the lowest voltage on the feedline compared to the highest voltage on the feedline... or visa versa.

There, I fixed it for ya.

DB, is this the video you're talking about from AT&T archives?

And the same question from another thread.

DB, I only found the video that 543 Dallas posted. Is this the video you posted before from AT&T Archives instead?

The video I was referring to was the one called Standing up for Standing Waves that 543-Dallas posted here.

The AT&T Archives video you are referring to is called Similarities of Wave Behavior (Bonus Edition), and can be found on the AT&T site here, and on youtube here. I have posted this video in the past, but I was not the original poster of this video.

imagine you and a buddy just erected your 1-10k antenna up the hill behind the house,
you have 500ft of rg213 running from the shack to your antenna,

you have no or insignificant common mode current on the braid and the plugs are fitted correctly,

your buddy sits in the tree & hooks his vswr meter right at the antenna feed-point,
he always measures at the feed-point, he won't have none of that coax stuff messing with his readings,

you run back to the shack & hook up your identical vswr meter to the rig with a double male connector, tune to 27.205mhz and key the mic,

1.2:1 says your meter in the shack,

what vswr does your buddy's meter read ?

I studied this for a while before figuring out the puzzle - Both trains arrive in Chicago at the same time.
