Topband: 160m dethroned? 600m the new top band?

Didn't I read somewhere that this band only allowed 1W ERP and antennas less 
than 10m  high or am I thinking of another allocation?

  Things are looking good at WRC-12. Approval of an international
  amateur radio allocation around 470 kHz seems very likely:

  This does, of course, lead to the question of antennas.

  What can people without a few acres to dedicate to 600m do to
  get a vaguely decent antenna?

  I started modeling an inverted L with an FCP and a loading
  coil the size of a rain barrel.  Then I added more top wires,
  in more directions, and the loading coil is only half the size
  of a rain barrel :)

  Before loading coil losses, gain is about -10dBi!

  Nowhere near as easy as 160m, but this could be a very
  interesting antenna challenge for hams...
