WINB estimated coverage arcs

The primary coverage arc is for signal levels above 40% of main beam maximum field, which occurs in the main beam direction. The areas marked secondary to the south and northwest are side lobes with fields about 20% of the main beam maximum. The area marked secondary to the northeast of the station is the rear lobe at fields just below the other side lobes.

At the long range, the main beam hits Eastern Australia and New Zealand. The rear lobe hits the Mediterranean area of Eastern Europe.
