All FM transmitters produce harmonics at even multiplies of fundamental frequency. If your harmonics fall on or near TV channel, air service or maritime frequency you could cause severe interference on that channel.
Use of a low pass filter is the best method of eliminating this kind of interference. These filters are well suited for use at power levels up to 1000 watts.
