More and more!

In April I could write here, that with this radiator of 1m x 1m  four bands can be worked.
Since yesterday there are 8 Bands, as now also 
10-12-15-17m
  are now included:
And with an SWR of 1:1 on each band, and a so far never achieved efficiency for short antennas.
On 20m the efficiency is 92%, on the higher bands even higher. 


 


I could test the the capability of this antenna yesterday. Within 30 minutes (21.45h to 22.15h) I made
in SSB the following contacts from the car:
10m:
        ZZ2T,  Sao Paulo, Brasil
        PT7Z,  Eusebio, Brasil
        ZW8T, Teresina, Brasil
15m:
        PR7AA,    Recife, Brasil
        CX3DK,   Uruguay
        FG5DH,   Guadelupe
        EA8AJO, Canary Island
        YB4IR,    Indonesia QSL see here
        RM4HZ,  Toljatti, Wolga, Russia
       
20m:
        UR7EN   Ukrain, Russia
        UX1UA       "           "
        YP9L      Romania
        UT4UO   Ukraine, Russia
        EA5IC    Valencia, Spain
        J48A      Aegina Island, Greece
        5B4AIC  Cyprus
        LZ7A     Sofia, Bulgaria
All received reports were  S9, with one exception: S7

Here are the SWR diagrams for 10, 15 and 20m:





Red curve = SWR, green curve = Impedance Z
