Typical HF antenna big signal levels?
(1/1)
sv3ora:
What are typically considered big signals on an HF antenna?
How about 100mVpp?
How about 10mVpp?
Are these really big signal levels that would be expected to be received by an antenna from these S9+60dB commercial stations?
(I want to design an RF preamplifier and I consider the typical maximum levels that one would encounter, so the amplifier not to distort the signals)
wn1fju:
The accepted convention is that an S9 signal is -73 dBm, or 50 uV (into a 50 ohm system). So an S9+60 dB signal would have a voltage 1000 times that, or 50 mV.
