In 2017, the Northern Black Forest Group DR9A in Germany won the multi-op section in the IARU Region 1 2m contest. This is held in September every year.
The photo above shows the 144 MHz antenna system. Lower down on the mast, there are 4 high stacks of medium gain 6-element Yagi's pointing in fixed directions every 45 degrees. At top of the mast, there is an array of 4 high gain 17-element Yagi's for when more gain in a particular direction is needed.
These are the top 20 stations in the results...
The DR9A contest station operated from the JN48EQ in the south-west corner of Germany. As you can see from the map below, it is pretty much in the centre of western Europe with stations in all directions.
The short video below gives a flavour of what the contest was like...
