Every now and then, a really special antenna system gets installed and usually it is a result of desire, commitment and dedication of the station owner. Kari, OH2BC is one of these guys.
Several years ago, Kari installed 8 x 18el X-pols (9v/9h) for 144.146MHz . Impressed by their stability and being able to use them in all weathers, he asked us to produce similar, this time for 50MHz.
Below top is his new Array. We supplied the antennas, cabling and power dividers, the H-frame and guying all prepared and installed by Kari and his team.
The system looks impressive but once you factor that those booms are 10m long and on a cross boom of over 21m wide, you begin to realise the work that had gone into this system.
Congratulations Kari, another Big Gun joins the 6m band party!
