100 ... 125 mW

The antenna directional characteristic should not concern a surface,
if Grid that it is impossible, multipatch :(
Also are impossible 5.5M and 11M ....

Now works link@41km 80Kbyte/sec OR 0.8 MBit
GL2411AP,Antennas -> Grid, multipatch ...

multipatch ...

Ok !!

The built-in dynamic power sensor in SmartAmps adjusts
the Radio Frequency (RF) power output level by reading the
input signal power.

It is a problem RF, multipatch ...

Told about such link,
however I did not see by their eyes.
