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.
