               Originally the two antennas were tested by receiving of the Beacons (propagation 
                permitted!). It was noticed fairly clear difference in the direction 
                of the antennas. However the major test what I waiting for was 
                waiting for me the ARRL September VHF Contest. 
                11 September 2021 and 12 September 2021 - at the days it was no 
                any propagation at the 6- meter band. No any beacons, no any stations... 
             | 
             
               Everyone who uses the band knows that at propagation 
                the amateur stations and beacons are very loud. But it was not 
                on the September' days of the 2021... No any propagation... Just 
                loud roaring from the solar flare of the geomagnetic storm... Will wait for the next 
                propagation to test the antennas.
