I was measuring and testing my newly improved Mini 9:1 UnUn transformer for the EndFed Random Wire antenna. (www.sk-tech.sk/om0et/mini-9-1-...) In this transformer I have used much thicker wire (1mm) and 8 trifilar turns instead of 5 trifilar turns in my previous version. The SWR measurement was done with MINI 1300 Antenna Analyzer. I've used approx. 16,2m (53ft) long radiator wire and about 17m (56ft) long counterpoise wire. Radiator wire still need's to do a lenght adjustments due to very high SWR on some bands and low SWR peaks located out of the bands.I wanted to do an ON-AIR test, but radio propagations was deeply degraded by running Geomagnetic storm (my wrong timing). I found just 2-3 stations on 20m and some more strong stations on 40m. 80m was still attenuated due to early time. Unfortunately just started raining... :-) I hope for better conditions in the next time ;-) Thank you for watching this video and 73! Paul OM0ET.
