ON0VHF 2m beacon 144.418MHz

The 2m beacon ON0VHF seems to be copyable at all times at a distance of just over 350km.  It is located just the far side of Brussels.

Imagine my surprise when I found out it is only running 15W to a single big wheel antenna with a gain of around just 3dBi. At one time I was considering a stacked pair of big wheel antennas here. In theory, properly phased, a pair of big wheels should give omni-directional horizontal gain of around 5dBd, which is similar to a small beam without having to turn it.
