Now that the FCC has established rules and regulations for the 630 and 2200 meter amateur radio bands, radio amateurs can now expand their contacts with frequencies below the standard broadcast band.

One of the prime concerns related to these bands, besides running low power and non-interference for existing services, is the type of antenna suitable for such low frequencies.

It's possible to design a relatively small vertical monopole antenna that will perform well in the rf "basement", thanks to this antenna simulator for 472 kHz.

Although this simple calculator isn't a replacement for software such as EZNEC, it will give you an indication on how this type of antenna will perform.  Just plug in the raw data about antenna type, antenna dimensions, and estimated ground losses, and you'll have a good, general idea of how much wire you must use for the 630 meter band.
