Hi @dsj,
The next extra long distance test is to mount the hub onto the top of my pole and test the Sky at the distance. (The preliminary tests were with the Sky on the pole and the hub in the distance)
This is the plastic box (with some drain holes) using 12V supply to a 5V buck converter to reduce voltage drop and to ensure any voltage drop in the feed wire is corrected.
(The two Skys on the new timber mount are testing vibrations and wind reading comparisons)
(And the windsock has also moved and changed design.)
The RSSI of the hub reduced to -84 going through the iron roof, and perhaps my solar panels and a ceiling and floor to the router on the ground floor. ( I could move the router if needbe)
My first test with the Sky on the distant headland at around 5km produced RSSI -85 with no problems.
So I am now ready to begin distributing my Skys to their distant locations…
And yes lightning might wipe the hub out…
cheers Ian
