Here is another link to a site dealing with compact antennas
including the coffee can antenna, cone disk, bicone and eh antennas.
There are a number of useful Javascript calculators here as well.

Check out the "What Can Small Antennas Do?" and "Per request - Pages
from old Web Site" links on this site.
The emphasis here is on ham radio and antennas that can be used for
transmitting as well as receiving. The instructions for tuning with
an impedance bridge can probably be ignored if the antenna is only to
be used for receiving. Tuning "by ear" will probably work just as
well.
Much of the criticism regarding compact antennas such as these stems
from the fact that they exhibit a loss compared to a full-size dipole
or vertical. That is true... so do MagLoops. OTOH, they also have a
reputation for lower noise in receiving applications.
