    • 50 Ω Dummy
    Load
    Amateur/Ham/CB radio use and experiments
    This dry dummy load has been designed to provide constant 50 Ω
    impedance to a radio transmitter to allow off air tests and experiments.
    Constructed of high quality PCB material and using 20 x 1KΩ 3
    Watt Metal Film resistors a SWR of 1.1:1 is possible from 1MHz – 30 MHz, the
    SWR increases to 2:1 above 50 MHz
    Please Note:
    The resistors if  color band coded will use either the 5 color band system,
    or
    the older 4 color band system. We may also use carbon film resistors that are coded with the value rather than color bands.
    The dummy load is air cooled and capable of absorbing RF
    energy of 40-50 Watts continuously for 1 minute, and up to 100 Watts for several seconds.
    Load incorporates a measuring port consisting of a capacitor
    (650 V DC rating) and diode (BAV21) with output banana jacks allowing the load to be connected to a voltmeter, and with a simple calculation the output
    voltage is converted to output power.
    See photos for details on the calculation
    and connection of test meter.
    Connection to the dummy load is via a high quality BNC jack
    mounted on the PCB.
    The PCB measures (approx.) 2.5” x 3.75” – this size makes the
    load able to be mounted in a quart paint can filled with non-toxic mineral oil
    or a wide mouth pint Mason jar similarly filled.
    Please
    note:
    Neither paint can, Mason jar or mineral oil is included in this sale,
    only the dummy load.

    Supplied as a finished PCB with all components mounted on the
    board this compact radio accessory is ready to go out of the box.
