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

[Rik van Riel]

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...
