Reflections about a remote shortwave listeners station

A TP-Link TL-WN8200ND 300Mbps Wireless USB Adapter provides a perfect connection to the access point 370 meters away. The adapter, hidden behind an aluminum cover, receives the signal at about -70 dBm. Both antennas provide a gain of 5 dBI. The access point is in free visibility. An initial 18 dBm Yagi antenna is not necessary at the moment. The further development determines the nature of the garden area. If visibility is obstructed by trees or branches, reinforcement may be useful.

The farthest station I've logged on medium wave, over a distance of 12932 km: Radio Belen from Puerto Montt. The 5 kW transmitter from the province of Los Lagos could be received on 25.03.2018 between 01:41 and 02:05 h UT on the frequency 1400 kHz with the ALA 1530 S + Imperium. A short time later took CBG Gander CAN again the frequency.
