The DMU-2000, a band scope for Yaesu FT-2000, has a function to plot SWR of the antenna connected to the FT-2000.
This is SWR plots for 40m band, antenna is Create Design AFA-40, 2-el HB9CV.
The left edge is 7000KHz, the red line is 7100KHz.
The SWR seems pretty low between 7000-7100. But above 7100KHz, it becomes very high.
So, I must use antenna tuner when I will QRV at above 7100KHz from coming April after the 7100-7200 band is permited in JA on 2009-3-30.
Here is the SWR of 20m band , antenna is HEXBEAM.
I bought normal setting HEXBEAM so that the SWR is optimized for phone band.
