RigExpert Antenna Analyzers
RigExpert Antenna Analyzers are powerful antenna analyzers designed for testing, checking, tuning, or repairing antennas and antenna feed-lines. Mainly, these are SWR (Standing Wave Ratio) and impedance measurement instruments (vector impedance analyzers). Their large, bright LCD screens provide graphic illustration of SWR, impedance; return loss, and much more. Easy to use measurement modes, as well as additional features such as connection to a personal computer (to plot SWR, R, X and Smith charts, etc.); make RigExpert Analyzers attractive for professionals and hobbyists alike. They are compatible with several operating systems, including Windows© 10, 11 and Mac, with software download*. The graphic display of various parameters over a wide frequency range is a key feature of these analyzers. This significantly reduces the time required to adjust an antenna. ZOOM models allow you to zoom-in on graph points for clearer analysis. USB connection allows export of sweep files with Antscope for Android or Antscope2 software to PC or MAC. *(download from the manufacturer https://rigexpert.com/products/software/). Many models have Bluetooth for direct file transfer for galvanic isolation without a USB cable, which provides the most accurate measurements. RigExpert Antenna Analyzers are available in several models with greater frequency range of operational features. Some have SO-239 UHF female connector, except for most models that operate at 230 MHz and above that have a Type N female connector. An array of options are available to cover almost any need for the professional and the Amateur. The following tasks are easily accomplished by using RigExpert Antenna Analyzers: * Rapid check-out of an antenna * Tuning an antenna to resonance * Antenna SWR and impedance measurement and comparison before and after a specific event (rain, hurricane, winter, etc.) * Making coaxial lines or measuring their parameters * Cable testing and fault location * Measuring capacitance or inductance of reactive loads *Send data to laptop for larger graphical display and further analysis. Note: For additional product information, please look at the files under the "Documentation" tab. When you need a versatile antenna analyzer for Amateur Radio or professional use, you'll find that one of these RigExpert Antenna Analyzers, from DX Engineering, will be well suited to the task!

Elecraft W2 Wattmeters
Elecraft W2 Wattmeters are versatile, auto-ranging power and SWR meters with simultaneous, fast response dual bar graph LEDs. Keep track of transmitter, amplifier, and antenna performance with this compact and attractive display that will fit just about anywhere in the shack. It requires only 10-14 Vdc and sensor cable connections. The W2 features two sensor inputs, an over-range alarm, a fully isolated amplifier keying cutout relay and amp keying control. PC remote connectivity is supported with the included USB cable. Read both power and SWR with higher accuracy, as well as set and check alarms, turn the LEDs off, and use for remote operations, all via computer. Included with the Elecraft W2 is one remote RF power sensor, for 1- 54 MHz or 144-450 MHz, which can be placed near the transceiver or amplifier output, minimizing coax cable length. Two sensors can be connected to the W2 to monitor different transmitters or amplifiers, switch-selected from the front panel. Also known as Directional Couplers, sensors have standard SO-239 connectors (UHF female) and connect to the display with standard CAT5 cables, also included. Accommodated by the second sensor input, additional sensors are available separately for a secondary radio, amplifier or alternative frequency coverage. DX Engineering stocks all six versions of the Elecraft W2, three as factory-assembled and tested units, and three as no-solder, easy-build kit units. All versions include one remote power sensor. Choose from the 1-54 MHz, 200W version or the 144-450 MHz, 200W version, both with 2/20/200 watt ranges; or the 1 -54 MHz, 2kW version for 20/200/2000 watt ranges. Offering accurate and efficient SWR and power metering for in-shack and remote operations, Elecraft W2 Wattmeters are an excellent choice. Order yours today from DX Engineering.
