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.

Palstar PM2000A Watt Meters
Palstar PM2000A Watt Meters measure and display SWR, forward power up to 2,000 watts, and reflected power simultaneously on a dual movement meter system that operates in the frequency range from 1.8 MHz to 60 MHz. Accuracy of the readings is assured with the PM2000A shielded directional coupler. These backlit meters, which can display average or peak power readings, now have a convenient peak hold function and a push-button selection for 300 watt and 2,000 watt ranges. PM2000A Watt Meters are the improved version of Palstar's best-selling WM150 Wattmeters. When QST tested the PM2000As' predecessor, they found it to be the only wattmeter with true Active Peak Reading. The PM2000As are one of the new generations of watt meters from Palstar. All of the features of the WM150 are integrated into PM2000A meters, now with increased power capability up to 2kW and two-second peak hold metering. To top it off, just like on Palstar tuners, the PM2000A meters have an 11 ga. (0.090 in.) iridite-treated aluminum case with a powdercoated front panel and top cover. Rear panel SO-239 (UHF female) connectors are provided for coaxial cable RF input and output, and a 2.1mm connector provides input for 12 Vdc at less than 200 mA to run the meter circuit and backlight. Note: For additional product information, please look at the files under the "Documentation" tab. Simple to hook up and use, Palstar PM2000A Watt Meters take the guesswork out of your inline RF power and SWR measurements. Order yours from DX Engineering today!
