[Elecraft] K2 tuner and G5RV

[Brian Alsop]

Ariel,

Please explain to me how your SWR measurements translate to ERP.

There are a whole bunch of things potentially between your rig and the 
antenna.  Then of course there is antenna pattern.

I once had a summer job at Airborne Instruments Labs.  Part of the 
"summer trainee" job was to listen to lectures from some of the engineers.

One particular engineer knew hams worshiped SWR.  He showed us their 
latest satellite antenna.  It had a 5:1 SWR few relative to 50 ohms. 
Their measurments showed no measurable loss due to mismatch.   Why? The 
length of the feedline was 6".

> I second Gerald.  The Zs6 is a much more efficient antenna and provides a better balance of performance.  I got DXCC on the G5RV but I got DXCC  - QRP on the ZS6BKW.  I took comparative measurements of SWR using an AA-200 analyzer between the two and you can read it on my blog at http://www.ny4g.blogspot.com.
