The YA-1 Low Pass Filter operates within the 1.8-29.7 Mhz frequency range. It has been rigorously tested in independent lab tests, demonstrating a minimum attenuation of 80 db or better for harmonic radiation in channel two and higher. This filter is designed to handle a power output of 1.5 KW, capable of withstanding up to 5 KW peaks when the Standing Wave Ratio (SWR) exceeds 2:1.

Engineered for efficiency, the YA-1 Low Pass Filter ensures that harmonic radiation is effectively suppressed, meeting the stringent attenuation requirements set by independent lab tests. Its robust design allows for reliable operation within the specified frequency range, providing a high level of performance for amateur radio operators. With a power rating of 1.5 KW and peak power handling of 5 KW under SWR conditions exceeding 2:1, this filter offers a reliable solution for maintaining signal integrity and minimizing interference. 

In conclusion, the YA-1 Low Pass Filter stands out for its exceptional performance in attenuating harmonic radiation and maintaining signal quality within the designated frequency range. Its proven capability to handle power outputs of up to 1.5 KW, with peak power ratings of 5 KW during SWR conditions above 2:1, makes it a reliable choice for amateur radio enthusiasts seeking optimal filtering efficiency and performance.
