50 Ω Dummy Load<br>Amateur/Ham/CB radio use and experiments<br>This dry dummy load has been designed to provide constant 50 Ω impedance to a radio transmitter to allow off air tests and experiments.<br>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<br>Please Note:<br>The resistors if  color band coded will use either the 5 color band system,<br>or<br>the older 4 color band system. We may also use carbon film resistors that are coded with the value rather than color bands.<br>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.<br>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.<br>See photos for details on the calculation and connection of test meter.<br>Connection to the dummy load is via a high quality BNC jack mounted on the PCB.<br>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.<br>Please note:<br>Neither paint can, Mason jar or mineral oil is included in this sale, only the dummy load.
