20W Dummy Load
$33.00
This 20-watt, 50-ohm dummy load presents a perfect match to your radio for all amateur radio HF frequencies from 80m to 10m, and also serves as a basic power meter.
Description
This dummy load, built with a custom case and containing the QRP-Labs 20-watt dummy load/watt-meter circuit, will present a perfect match to your radio’s 50-ohm antenna connector. This will allow you to test your radio and/or software without fear of damaging the radio. It also serves as a basic power meter when used in conjunction with a volt-meter. As measured with a RigExpert Stick Pro, this dummy load presents the following SWR on the ham bands: 80m–1.00:1, 60m–1.00:1, 40m–1.01:1, 30m–1.02:1, 20m–1.03:1, 17m–1.4:1, 15m–1.06:1, 12m–1.10:1, and 10m–1.11:1.
MEASURE POWER OUTPUT
You can also use this dummy load to get a good approximation of power output. To measure power output, insert a volt-meter’s probes about ¼” into the negative (-) and positive (+) probe holes on the top of the case and measure the voltage while transmitting. Use the graphs that come with the case to measure the approximate output power of your transmitter.
