I think so…
The portable unit at the 166km range test was showing 0% signal strength but when I got back to the other node on the fence it was showing the signal being received at 35% I think that was partly due to the antenna on the node on the fence not being as efficient as my portable units this is what it looks like on my nanovna:
Portable:
Fixed (Unit on the fence):
The portable unit is showing a swr of 1.04 at 860mhz where as the fence unit was 1.44, so much worse.
I am still an very much an beginner with antennas but from my testing the portable antennas are decent.
I am not sure if they ship internationally they are New Zealand based company so local for me (no affiliation)
As always with super long range testing LOS is the most important factor the earth being a globe doesn’t help
