Dynamic Antenna HF 50 to 7 Mhz - Kohjinsha Mod. KA1-406S
Good Morning to all, after what happened the night between 21/22 December 2023 where an atmospheric event of exceptional magnitude, Foehn winds that reached a speed of 220 km per hour (140 miles) and destroyed my Antenna system that I was very fond of, see Antenna Disaster, consequently forced cessation of activity in Radio, I found myself having to decide what to do, which antenna to put to resume my activity in Radio, because it is clear, that for me the activity in Radio is so rooted that no one and nothing in this world will ever be able to make me give up continuing this wonderful and rewarding hobby. How to restore my Antenna park to the same level as the Quad 5 el. multiband + the two Yagi Antennas 3 elements in 30 and 40 m.? which is not exactly easy .... my choice was a careful and prudent choice on what the international market offers in terms of Antennas, to have the maximum performance in my opinion there are two choices, the first is to orient yourself towards monoband antennas or at most dual-band antennas, but the cost increases a lot considering that there are many bands (from 6 to 40 m.) and to do an excellent job you would need at least 2 Towers if not 3, to conveniently space all the Antennas, something to be excluded for me given the costs; so in my opinion there is only one solution left: the new Dynamic Antennas. There are many companies that produce them, see the American SteppIR, the Japanese Versa Beam by Kohjinsha, the Italian AD Antenna Dinamica and Ultrabeam. After a careful selection of the various models and based on my needs, my choice fell on the Japanese Kohjinsha Versa Beam, in the KA1-406S model. This antenna has a 10 meter long boom, 5 elements from 6 to 20 m. plus 3 elements in 30 and 40 m., at 6 m. I also added the kit of 2 passive elements which brings to 7 elements on this band, I hope I have made a good choice, I trust in Japanese products and from research done with several Versa Beam owners, the opinions that emerged on these Antennas were very very good, the Antenna arrives by air at the Turin / Caselle airport in the first ten days of September, after I will assemble it and test it, stay tuned, as soon as possible i will publish all details/install of this new Antenna KA1-406S, I hope I have chosen the best, Many Thanks Hiro San.
