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!

4O3A 8xAB Antenna Switches
4O3A 8xAB Antenna Switches integrate eight independent A/B switches into a single compact unit, enabling seamless switching between multiple antennas and radios. When paired with two 403A Antenna Genius switches (O3A-40-AG8X2 or O3A-40-AG8X2-N), it forms a powerful 8×4 antenna matrix, allowing up to eight antennas to be routed to four radios with exceptional isolation. Built with the needs of high-power stations in mind, the 8xAB Switch delivers robust performance, intuitive operation, and a clean, maintainable installation. The primary motivation behind the 8xAB switch is the integration of two Antenna Genius smart switches into an 8×4 Super Switch.

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.

Davis Instruments UV Radiaton Sensors
Davis Instruments UV radiation sensors measure the portion of the UV spectrum to which human skin is sensitive and is known to cause sunburns. These sensors allow you to display the UV index, dose rate, and daily and accumulated doses. A special multi-layer filter provides a UV spectral response that closely matches the Erythema Action Spectrum. An included diffuser provides excellent cosine response, resulting in higher accuracy regardless of the solar angle. Their 2-piece housing minimizes radiation heating, allows for convection cooling of the sensor, and prevents the trapping of water or dust. These sensors include 2 ft. (0.6 m) of cable for mounting to the ISS. To mount one of these UV sensors next to a rain collector, add the Sensor Mounting Shelf (not included). If you or a loved one is sensitive to UV due to nature or prescriptions, or perhaps are a skin-cancer patient, then one of these Davis UV Radiation Sensors, coupled with a Vantage Pro2 weather station, could provide greater value than you might imagine.

Low Band Systems HF Transmit Band Pass Filters
NOTICE: Due to materials supply and logistical issues, resupply of Low Band Systems products will be delayed for an indefinite period. Low Band Systems HF Transmit Band Pass Filters are very high quality multi-stage devices designed to specifically limit the RF band pass to a single Amateur band. They eliminate image and harmonic RF interference issues for dedicated mono-band operations in multi-radio contesting environments. Required for use with transmit multiplexers, these passive filters provide the additional isolation needed to allow multiple transceivers to be operated on different bands simultaneously on the same antenna. Used individually on mono-band radio and antenna combinations, these filters provide the isolation required in multi-radio contest stations. Low Band Systems band pass filters are available for each of the ten HF Amateur Bands in 200, 500 and 1,500 watt models, and 2,000 watt models for the main contesting bands of 160, 80, 40, 20 ,15 and 10 meters. Their unique aluminum enclosures, some with fans, are laser cut with "Perfo-Box" on the side and their power handling and band of operation are stenciled chassis cutouts in European nomenclature, such as "3,5 MHz" for the 80 meter filter, for example. Their permanent demarcation allows immediate identification, preventing any future trouble with faded or missing printed labels. Supplied only with standard UHF Female/SO-239 connectors, these HF Transmit Band Pass Filters achieve over 60 dB of out-of-band suppression that virtually eliminates out of band noise and interfering signals. They are designed to provide a sharp roll off just outside each Amateur band; just below 3.5 MHz and just above 4.0 MHz for the 80 meter filter for example. Low Band Systems filters are the first choice of major multi-multi contest stations around the world! They provide the clear benefit of a dramatically lower noise floor for enhanced single-band weak signal reception desired for elite contest and Field Day operations. Low Band Systems Band Pass Filters are used in conjunction with their multiplexers, also known as multi-band transmit combiners. Low Band Systems Diplexers, Triplexers, Quadplexers and Pentaplexers, also available from DX Engineering, provide good levels of isolation between band ports, but band pass filters are also needed for multi- transmitter operation. This is because the multiplexer's main purpose is to balance the impedances for the multiple-transceiver/single multi-band antenna stations. They provide UHF Female/SO-239 connections for multiple 50-ohm transceivers to be connected to a single 50-ohm feedline. So, band pass filters are REQUIRED for each multiplexer band input to provide the additional isolation required to allow multiple transceiver setups to work. The transceivers for each band are connected to their associated band pass filter, and then to the multiplex device such as a triplexer, which is connected to a tri-band beam, for example. All transceivers can operate simultaneously with up to 80 dB of isolation, unhindered by the signals from the other connected radios operating on the other bands on the same antenna! Achieve the advanced operational advantages that these exceptional filters and multiplexers provide. Order Low Band Systems HF Transmit Band Pass Filters from DX Engineering! NOTE: Filters made for 160 meters are 2.0 MHz low pass models to prevent harmonics on higher bands. They do not reject frequencies below 1.8 MHz. If AM broadcast interference is a problem, an additional BCI filter should be used. After better antennas, these filters are suggested as the most important multi-radio station upgrade by top contest station builders and operators. Low Band Systems HF Transmit Band Pass Filters simply allow more contacts to be made with worldwide DX stations and DXpeditions.
