Antennas-Amplifiers LPF30 HF Low Pass Filters
Product Line Title: Antennas-Amplifiers LPF30 HF Low Pass Filters Antennas-Amplifiers LPF30 HF Low Pass Filters are designed for use with legal-limit linear amplifiers up to 2kW. They operate across a passband frequency range of 1.5–29.7MHz with a low insertion loss of 0.07dB, maintaining signal integrity while suppressing harmonic frequencies generated by the amplifier. These filters feature a 50-ohm nominal impedance and come equipped with SO-239 coaxial connectors. Precision-tuned and verified using a calibrated HP8753ES network analyzer, they deliver low return loss and consistent attenuation performance. The LPF30 Low Pas Filters support flexible mounting in any position with the included 5mm mounting holes. Exceptional Performance is achieved through careful design, tuning, and component selection.

Antennas-Amplifiers 6344 Double 2x200W 2m & 70cm Bandpass Filters
Antennas-Amplifiers 6344 Double 2x200W 2m & 70cm Bandpass Filters are a dual band, dual power 2×200W band pass filter engineered for clean, interference free operation on both 144–148MHz (2m) and 430–450MHz (70cm). This "double" filter design incorporates two independent high power bandpass sections, each rated for 200 watts, providing exceptional filtering performance for stations using a single feed dual band antenna. Built to dramatically reduce unwanted signals, the 6344 suppresses not only HF, 6m, 4m, and FM broadcast interference but also problematic intermediate VHF/UHF frequencies such as 170MHz and 210MHz, as well as key harmonic ranges including 288MHz, 720MHz, 880MHz, and more. The result is a cleaner signal path and significantly reduced receiver overload in busy RF environments. With very low insertion loss on both amateur bands, the filter maintains full transmit and receive performance while sharply attenuating out of band energy. Its dual band architecture makes it especially ideal for use with 2m/70cm dual band antennas that use a single connector, providing excellent front end protection without complicating station layout.
