From inside a metal building,on a unused frequency, you won’t really be bothering anybody. See FCC rules about unlicensed radios.
Defective – Open circuit This is supposed to be a 50 ohm dummy load.It is an open circuit, very bad for the finals on a transmitter.The design uses the aluminum case as the ground connection for one end of the resistor. The case must be oxidized of coated.Do not buy this product. You can get the same functionality by not attaching anything to the output of your transmitter.
One of the must have items for any ham radio operator Dummy loads and antenna analyzer are the two tools you’ll go to everytime your radio gives you hiccups. The dummy load simulates a perfect antenna that can be used a reference point.I was originally going to give this a zero star review because it arrived to me open circuit. Inside a dummy load is a resistor. A non-inductive, pulse withstanding resistor, typically of this price level its a carbon composition or a carbon pile with horrific temper coefficients, but still. a 50 ohm 10%…
