    • Coaxial construction 50 Ω Dummy
    Load with SO-239 UHF Socket
    Useful for Amateur/Ham/CB radio use and RF experiments
    Brief Description
    This dry dummy load has been designed to provide constant 50 Ω
    impedance to a radio transmitter to allow off air tests and experiments.
    The coaxial construction creates a load that presents a more stable resistance to the transmitter output over a wider range of
    frequencies, testing has shown the following SWR measurements using a RigExpert AA-230 Zoom, +/-:
    3.8 MHz  – 1.01:1
    7 MHz     – 1.02:1
    30 MHz   – 1.07:1
    50 MHz   – 1.16:1
    70 MHz   – 1.22:1
    145 MHz – 1.60:1
    Constructed from high quality PCB material and using 20 x 1 KΩ 3
    Watt Metal Film or Carbon Film resistors (see photos)
    the dummy load while air cooled is capable of absorbing RF energy of 40-50 Watts continuously for 1 minute, and up to 100 Watts for several seconds. The load can also be mounted in a can with oil for longer use at 100 watts. Mounting holes in the PCB can accommodate 4/40 bolts that will allow the load to be mounted on a can lid. Some details on how to do this are in the user guide (available on request prior to sale if needed).
    Connection to the dummy load is via a high quality SO-239 UHF Connector mounted on the PCB. Overall dimensions are: 2.5″ diameter, 3/4″ thick (PCB sandwich, excludes SO-239)
