External antennas like the AN-101 significantly improve shortwave radio reception compared to built-in telescopic antennas, particularly on 25-meter and 31-meter bands, though signal amplification also increases static noise, demonstrating the fundamental trade-off between signal strength and noise in radio reception.

AN-101 Antenna Performance: Shortwave Radio Test #shorts追加:
That would be That would be great if we can use this AN101 antenna on the shortwave to see the performance of that feature. Not much activity going on. Go on 25 11 25 meter band 31 meter band. External antenna is working good. But regardless, this uh external antenna which can be hooked outside the apartment balcony and bring the cable and attach like that for the uh trying to listening the distance station, the built-in telescopic antenna is also sufficient enough to receive uh strong stations even even weak weaker stations in the high propagation times.
I'm going to try something to see the activity there. We found some station on 25 meter band 11645. AN101, let's see.
Maybe better.
Much better. Very useful. Of course, when you amplify a signal, the noise is also a byproduct. So, you also increase the static noise. But somehow, the attenuation helps reduce the noise. It kills the signal also. So, we have some activity on 31 also.
