I have never understood “the thinking” with many Ham’s when the discussion of Dummy Loads comes up. Some Ham’s will tell you, the minute they hear you tune up on a frequency that you just made a QRL inquiry on, “GET A DUMMY LOAD, WHAT ARE YOU TUNING UP ON THE AIR FOR”! Well, what if my antenna represents several hundred Ohms on one wavelength, and only several Ohms on another? I have a Bird Model 43 Wattmeter, and a Bird Dummy Load. From a “DC” perspective, it measures 50.0 Ohms. From and “AC” stand point it also measures 50.0 Ohms from 1.8 MHz to 902 MHz. It has very little error even at 1300 MHz. That is a good thing, because I depend upon it for real work, like assessing line losses etc!
