You may be getting too much signal...an attenuator might help.
You might be getting overload from nearby FM stations...an FM Trap designed to lower the entire (88-108) FM band might help. Note that some only attenuate about 95-108, which let's some channels still sneak thru and cause problems).
You might just have too darned much interference from other devices in your home. That happens a lot....getting the antenna to a spot where it can "see" the transmitters through a window can help, or just going outside with it.
Many digital devices, even the TV set itself, can interfere indoors. Switched-mode power supplies (those "universal voltage: 100/220 V, 50/60 Hz" ones) that are used on most phones, pagers, etc can interfere. DVR's often put out noise on upper-VHF channels, and so do some Cable boxes and satellite receivers. Computers, too.
