ARCALA EXTREMES AT OH8X Finishing the 160m 3el YAGI Monster
Today is the shortest day of the year - only three hours of daylight and as of yesterday the Arcala Extremes antenna’s last 160M element went up!
After working three weeks straight OH8SR and OH6RM went home for Xmas!

Please note the following technical details:

  • Tower height 100m
  • 80M and 160M booms 60m
  • Five (5) 80M full-size elements


You note in the picture that OH8SR and OH6RM are working inside the boom.

Poor OH8SR - with 2nd 160M element he was working in a total fog without seeing the ground for 7 hours! He seemingly enjoy working inside of the boom!

The upper slip-ring has such diameter that you can drive thru with Juha’s large Lexus!.

Radiosport on Extreme Level

Arkala 65.18N, 26.24E


Northern Taiga forests and wet mires surround the station and we can say that Arkala is the northernmost station for serious contesting in the world. Nearly all of Iceland, Alaska, Quebec and Siberia is south from us.

Urban life is 40 kilometers away and 125 m lower, in the city of Oulu by the Gulf of Bothnia, visible in the western horizon. The highest treetops and antennas in Arkala are over 200 meters above the sea level and therefore prone to 'Tykky', ice building up small water vapour and causing loads of up to 3-4 tons per tree crown. Every big antenna in Arkala has a special Tykky-hammer.

Arkala is on the edge of the boreal Auroral oval. Places like N1 and N2 share our geomagnetic latitude. The closeness of the oval makes radio-sprorting rather challenging...
