LPF7000 – Most FM transmitters produce harmonics at even multiples of your fundamental frequency. If your harmonics fall on or near a TV channel or Maritime frequency you could cause severe interference to that channel. The most common cause of fines from federal agencies is due to TVI or other interference from your transmitter which generates a complaint.
Use of an LPF-7000, 25 watt low pass filter is the best method of eliminating this kind of interference. The low insertion loss of the LPF7000 filters makes them well suited for use on power levels as low as 100 milliwatts on up to 25 watts! Includes our 30-day money-back guarantee and a full 2 year warranty!
