So today I tried an outside, flat, line of sight measurement , but could not get the mesh working with my cellular hotspot. See new topic.
So I had to do something at my house and got similar results to the above 230 m actually got 215 m (With the gateway Argon having both Antenna and the Xenon having the mesh antenna). About the distance of 12 residential homes in my area. (I was walking on my street, with the Argon near the road, up a slight hill.)
