proFIL 4151 Tunable Cavity Bandpass Filter. Manually tunable for lower NATO 1 band (225-325 MHz). Its low loss design and steep attenuation curve makes it ideal for base station use. proFIL 0100 series Power Line Noise filters is designed to reduce noise and interference from the switched mode power supplies. They attenuate effectively low frequency switching frequencies and higher harmonic frequencies caused by unintentional interaction with high power rf-transmissions. proFIL 1010 series Coaxial Cable Interference Filters are designed to minimize interference that is travelling backwards in coaxial cables due to antenna circuit mismatch, reflections around antenna and cable faults. If present, this interference shows erratic behavior in other electronics and electrical equipment like sporadic activations, data errors, clicks and cracks. It can also activate other transmitters and make them oscillating on other frequencies. In higher power transmitters it can create strong electromagnetic field inside the cockpit which can exceed even healthy limits. proFIL 1010 does not block DC-current thus it can be used in coaxial cables that supply control signals and DC power to the antenna tuner. Due to the innovative design of proFIL™ technology, pro
