As an antenna specialist and designer of antennas there are several unprovided key bits of information that will vary the answer. What kind of antenna are you using? Is it a dedicated FM Radio antenna - 88 to 108 mhz band or a TV antenna? How many elements (bars) on the antenna? Polarity - horizontal or vertical (do you have the antenna flat - in the horizontal plane, or vertical - all the elements pointing one side to the ground the other to the sky? Height above ground?
I have designed and built many antennas for different applications including a 6m long FM Radio antenna to pick up signals from a station more than 100 miles away with lots of mountains inbetween.
Polarity is important because if the FM station (and most do) transmits in vertical polarity and your antenna is horizontal you won't get much signal. There are a number of excellent dedicated FM antennas available at places like TANDY Electronics/ DICK SMITH/ Radio Shack.
Do you have a field strength meter or some way to determine the exact direction to aim your antenna? Bigger is generally better but sometimes you can get better reception with a stacked pair of smaller antennas as the longer the antenna the more directional it becomes and therefore direction is more critical. A stacked pair exhibits a theoretical 3db increase in signal gain over a single antenna, but if spaced correctly increases of as much as 4db have been recorded.
Signal booster amplifiers are not a good idea if you have any strong local TV or Radio stations as these will simply overload the amplifier. You can get from an antenna supplier (not a chain store but a wholesaler) a thing called a single channel amplifier that will amplify just the station you want, but they have to be specially made and will cost you heaps.
Contact me at kealoa9@yahoo.com and I will discuss this with you in more detail once I have discovered all about where you are and where the station is etc.

FM reception is limited by distance, transmitter power, your FM receiver sensitivity, and your antenna gain. You have little control over distance and transmitter power. If you have a quality FM reciever and an external FM antenna with directional gain, perhaps with an amplifier, this may help. The directional antenna is pointed towards the transmitter and focuses the signal level so it's higher at the receiver antenna input. Look for an external FM antenna from Radio Shack. Then install on roof outside. If you presently only have an indoor antenna, this will make a big difference. If this is for a car, then the only thing you can do is add an FM amplilfier. Sometimes it only add RF noise, sometimes it makes difference.

Make sure you have a good antennae.
Play around with the antennae,at different times of the day the signal does change,nightime is actually the best time to receive a good signal from fm stations.

FM radio travels more or less in a straight line. so distance is a huge factor considering the curvature of the earth. the height of there transmission tower makes a difference so logically the height of your receiver antenna will also. (average range for FM is about 75 miles) would like to note that AM is much longer range because it can bounce off the ionsphere which has a higher altitude at night

you require a high gain antenna for your radio - you cant connect it to your dish unfortunatley.
Check your lcoal hifi, radio shack or even walmart to see what they have in stock.
also plenty of websites out there for DIY antennas that you could make with simple materials
big issue with FM is line of site - if there are any large buildings o, hills or even trees near your location they will affect signal - you could also try a an old style tv arial installed on the roof of your house

Buy a FM radio signal amplifier/booster. You can get these at Radio Shack:

My pedestrian methods have included a coat hanger and some foil, but I think you should stop by Radio Shack, and get a booster antenna.

there are devices that will increase yhe capability of your receiver to receive the radio signal, you need a good receiver, and make sure that you are using a good am/fm adapter.
