How to Fix Poor FM Radio Reception

1. Remove obstacles you have control of Make sure
   your Antenna has as close to a line-of-sight
   "view" of the radio station transmitter as
   possible.
2. Check and replace antenna connections  Make sure
   antenna and radio connections are secure. Check
   for brittleness and fraying. If you have an
   outdoor antenna, cables can get worn when exposed
   to the elements or chewed on by pets or wild
   animals.

3. Run a frequency scan  If you have a stereo or
home theater receiver, after checking antenna
placement and connections, run a new frequency or
tuning scan (if this feature is provided). As the
scan proceeds, it will stop at every station that
it receives just press scan or tuning to
continue to the scan. This process also allows
you to mark your favorite stations via presets,
so you can access them directly instead of
manually tuning them in each time. Most stereo or
home theater receivers provide 15 or more presets
for FM stations 4. Switch from stereo to mono
 FM Radio stations often transmit both Mono and
Stereo signals. Although it is desirable to
listen to music in stereo, FM stereo signals are
a lot weaker than mono signals. Depending on the
station's transmission power and distance, you
may be able to receive a stable mono signal, but
the stereo signal may come in weak or not at all.

5. Use a rotor If you have an outdoor antenna
and receive radio signals from several directions
adding a rotor to re-position your antenna when
needed might help. However, this solution is
expensive with prices for a complete kit ranging
from about 100 to 200 or more.

6. Move your antenna If you have an indoor
antenna, placing near, or on a window will avoid
interference from materials used in wall
construction. Also, place the antenna as high as
possible. However, if the length of the cable
that goes from the antenna to the radio tuner is
too long the signal may be weakened. 7. Use a
signal amplifier If you are having trouble
receiving FM radio signals and you only have one
"radio", you can place a signal amplifier (aka
signal booster) between the antenna and your
receiver or radio to boost the signal. Just
connect the cable coming from the antenna to
input of the amplifier and the output to your
radio or receivers' antenna input.

8. Use a distribution amplifier or use a separate
antenna for each radio If you have more than
one radio, you should have a separate antenna for
each as splitting the signal will decrease signal
strength, especially if the cable distance from
the signal splitter and one or more radios are
long. A more practical solution is to use a
Distribution Amplifier. Connect the main feed
from the antenna to the input on the amplifier
and then connect the outputs of the amplifier to
your radio(s).

9. Get a signal attenuator If you are too close
to a radio transmitter, causing overload, an
attenuator can be used to reduce the strength of
the signal. The most common type is a small
inline unit that you insert between the antenna
and your radio that has a fixed amount of reduced
gain (3db, 6dB, 12dB). The hard part is figuring
out how much gain reduction you need. An
attenuator that has a continuous adjustment
allows you to set the amount of attenuation
(gain) that may be needed for different stations.
