Collinear antenna 1 and sleeve dipole antenna test results for LoRa/LoRaWAN tutorial 46
See: https://www.mobilefish.com/developer/lorawan/lorawan_quickguide_tutorial.html

Gateway ID            Latitude     Longitude   Altitude [m] Model                           Antenna Model            Placement   Google Map
eui-aa555a0000088013  52.438285    4.817652    42           Raspberry Pi with IMST iC880A   Collinear Omni 868 MHz   outdoor     https://www.google.com/maps/place/52°26'17.8"N+4°49'03.6"E

To find information about a gateway, using the gateway ID:
https://ttnmapper.org/colour-radar/?type=radar&hideothers=on&gateway=eui-0ba0000000000001
https://www.thethingsnetwork.org/gateway-data/

To find information about a gateway, using the latitude and longitude:
https://www.thethingsnetwork.org/gateway-data/location?latitude=52.46079&longitude=4.800586&distance=200

End node located at the 2nd floor (altitude ~11m):
https://www.google.nl/maps/place/52°27'06.2"N+4°48'39.7"E

The end node tx power is not reduced!
The end node is placed in front of a window at location A, facing East and South.

The collinear antenna is titled at angle α.
I am only interested in the results from gateway eui-aa555a0000088013.
