How does an AM Radio receive reception on the AM band? All AM
radios require an antenna whether it is internal or external, and in
some cases both. Internal AM antennas are located inside most radios
and consist of a bar or stick referred to as a ferrite.
The ferrite bar has wire coiled around it on
each side to receive Medium and Long wavebands. It is
then wired to the inside of your radio for selectivity. The
radio waves (if nothing interfering) come in contact to the ferrite
antenna. There is more to it then that but you get the basic
idea. When you position the radio in different directions you may
notice a change in reception. The ferrite antenna is
directional for receiving the radio waves coming into
In some cases the position of the radio or
the type of building or house you are in may limit the reception.
What to do if that is the case? What antenna do you need to improve
your reception? Depending on where you live, what building you
are in and how far the radio station is, searching for a good
AM antenna can be difficult.
Taking the time to try
different locations with your radio to find the best location
to get the best reception will help. Experimentation is the
best way to see how it works for you. Some portable radios have an
external antenna terminal for AM. If your reception is better
outside, try this quick and easy antenna: Use 50' of insulated wire
attached to the AM antenna terminal. (Caution: you may need a ground
wire attached to a grounding rod outside, depending on soil
conditions, may need metal rod driven into the ground 3 to 8 feet,
if you are in areas with lightning). Run the antenna wire inside
around a window or along a baseboard, or if possible, the wire
should be mounted outside at least three feet away from the face of
the building or it may not work. Or try Bob's Cheep AM antenna Bob's Cheep AM Antenna (require

Is that where you want the radio? If
not, then I would recommend the Twin Coil Ferrite Antenna (sold
by C. Crane) which is the best AM antenna on the market. This
will let you keep your radio next to your bed or in an area that the
radio waves can't quite get to. (Review by RadioIntel.com )
only need a little boost with reception where your radio is placed,
you may want to try the Terk Am Antenna (sold by C. Crane) or
a Select-A-Tenna (sold from various websites).
