But the percentage of messages >-3dB is a better way to determine gain.
Also, I have attached the report of the terrain near me. I assume the red stuff is saying I won't see very much there. I find that a bot strange as my antenna is about 107' above sea level and west of us is an estuary, some low lying sand dunes and then the Indian Ocean. SO I would expect visibility to the moon and back, so don't really know why I've got red over the water.
It will then draw outlines for your theoretical range for planes at 10000 and 30000 ft.
You need to zoom out with the - button on the bottom left to see it though.
The red stuff is "visibility cloak" which is something quite different.
Looks like you can see around 200 nmi, but i suspect that is for 30000 ft, it makes sense to check for 40000 ft
