What is a characteristic of a random-wire HF antenna connected directly to the transmitter?
It must be longer than 1 wavelength
Station equipment may carry significant RF current✓الإجابة الصحيحة
It produces only vertically polarized radiation
It is more effective on the lower HF bands than on the higher bands
الشرح
A random wire fed directly against the station has no separate return conductor, so the chassis, interconnecting cables and ground wiring serve as the other half of the antenna and carry significant RF current.
