  1. LDG control cable for Yaesu transceivers with "TX Req" input, suitable for various LDG tuners with 3.5mm stereo jack socket (radio). Tuning is done via the "Tune" button on the tuner, this signals the radio via "TX Req" to transmit a low power carrier. Red plug to the transceiver, black plug to the tuner.

  2. Rosmeter and Wattmeter Crossed Needles Freq. 144-470Mhz 15-150W PL-f connectors

  3. Rosmeter and Wattmeter Crossed Needles Freq. 1.8-30MHz 50-54MHz 130-200Mhz 30-300W PL-f connectors

      OUT OF STOCK  

  4. The SX20C is a compact SWR-power meter. Featuring cross needle design for measuring SWR and output power simultaneously. Compact size makes it very useful for testing mobiles as well as base station installation.

    Special Features:

    • Cross needle design
    • Rated from 3.5-30, 50-54, and 130-150 MHz
    • Power ranges of 30 & 300 Watts

      OUT OF STOCK  

  5. The SX40C is a compact SWR-power meter. Featuring cross needle design for measuring SWR and output power simultaneously. Compact size makes it very useful for testing mobiles as well as base station installation.

    Special Features:
    • Cross needle design
    • Rated from 144-470 MHz
    • Power ranges of 30 & 300 Watts

  6. Compact and accurate 3-in-1 OSL (Open, Short, Load) calibration kit for radio amateurs. It is also ideal for lab equipment, telecom

  7. Midland KW 520 Wattmeter / Rosmeter
    1.8 to 200 MHz and 140 to 525MHz

      OUT OF STOCK  

  8. The SX400 measures forward and reflected power and VSWR. Compact size makes meter useful for testing both base and mobile installations. PL connections.

  12. Inserted directly into the antenna feedline, measures antenna current in three calibrated ranges. Use the RF current meters for precise measurements of antenna currents, while tuning your amplifier or tuner, calculate the impedance of your antenna feedpoint. Highly suitable for experiments with antennas or monitor changes of the antenna during operation.

  13. The Z-100PLUS is an automatic antenna tuner useable for 1.8 to 54 MHz, for any transceiver with 0.1 to 125 Watt power SSB/CW (100W FM, 30W on 6m). The tuner is suitable for any unsymmetrically fed antenna (i.e. Beams, Dipoles, Groundplanes etc.). If the matching range is not sufficient, a 4:1 balun (symmetrical) or a MTFT balun (unsymmetrical) can be used (not included).

  14. The LDG KT-100 is an automatic tuner intended for use with modern Kenwood transceivers. It works with any Kenwood transceiver that supports the AT-300 Kenwood tuner (no longer available). A partial list of compatible units includes: TS-2000, 50, 450, 480SAT (not HX), 570, 590, 850, 870, 990 (and all variants). The interface cable is included.

  15. The AA-35 ZOOM is a portable, self-calibrating analyzer, designed for measuring SWR (standing wave ratio), return loss, cable loss, as well as other parameters of cable and antenna systems in the range of 60 kHz to 35 MHz, with incredible ZOOM capability.

    The following tasks are easily accomplished by using this analyzer:

    • Rapid check-out of an antenna
    • Tuning an antenna to resonance
    • Comparing characteristics of an antenna before and after specific event (rain, hurricane, etc.)
    • Making coaxial stubs or measuring their parameters
    • Cable testing and fault location, measuring cable loss and characteristic impedance
    • Measuring capacitance or inductance of reactive loads

  16. Automatic Antenna Tuner for FT-891.

  17. The analyzer is designed for measuring SWR (standing wave ratio), return loss, as well as other parameters of cable and antenna systems in the range of 100 kHz to 230 MHz.

    It is the world’s first antenna analyzer capable of 16 hours of continuous measurements without battery recharging.

    Small, handy and powerful vector network analyzer is designed for measuring most useful parameters of cable and antenna systems in the range of 100 kHz to 230 MHz. Compared with the other devices the Stick is the State-of-the-Art Antenna & Cable Analyzer. Because it has Key benefits: less size you obtain, less weight you carry, less time you measure.

  18. Reads SWR, forward and reflected power digitally in a single glance. 1.5-525 MHz, HF/VHF switch, 200 Watts.
