No where near as large as Australia with a much smaller population.

You should remember that Finland is a very mountainous country making VHF/UHF propagation extremely patchy. We have a totally different terrain. We do use SFNs such as in Cairns, Gold Coast/Sunshine Coast, Newcastle, Central Coast NSW, and a pair in Melbourne. The transmitters in these SFNs are low powered on small towers just like those used in mobile repeaters.
Remember also that Finland's analog TV switchoff is complete. We have not used VHF for SFNs, only UHF. Since the frequencies used in out SFNs are near that used for the phones, it is much better to keep the UHF transmitters away from the mobile phone cell receivers to prevent interference.

The VHF transmitters range from 1 800 - 3 500W ERP, using channels E5 - E12.
I wouldn't call the towers small, either.

The Finish transmitters are not high powered compared to our 50,000 W digital VHF transmitters. The table is in Watts not kW.
