The antenna
was tested in the Air. Of course it is not a 5 element beam but
it is works perfect for me. I worked with the antenna in HF WORLD
CHAMPIONSHIP, July 13-14. It was made 115 QSOs. Most interesting
QSO was made with New Zealand, ZM1A.
I worked with the antenna in RSGB IOTA CONTEST, July 27-28, 2019.
It was made 57 QSOs. I worked with the antenna in WAE DX TEST,
August 10-11, 2019. It was made 13 QSOs. These results are good
for working at 100 watts and staying in the test for about 12
hours.
|
The antenna was tested in the 50 MHz ARRL VHF test
where I successfully made one QSO with N4PN. On this Band I received
lots beacons from the USA and Canada.
So, the antenna works. I will use the antenna in
my operation in the Air and check the antenna behavior in the
winter months.
