er, 95mA idle current
but you prob figrued that out
so you looking forward to dear leaders summit?
or you think best korean gonna flake and send his sister?

lordpil's blog
it goes faster with less problems when you understand
problems are never really problems, theyre just delays, not much that cant be fixed or worked around
so its like 95w idle power
and 30mA actual output
see your math works okay if you know what to attach it too
yes make results, report back with graphs and pics

05:43:00 < monkeyisl> Transmitting current 95mA@0dBm
monkeyisl, if it takes 95mA to drive 1mW, its probably going to take more thyan 30mA to drive 100mW
it should be
dB maths kind of assume rms values in most situations
it doesnt have to
you could have dB_cats_vs_dogs
but generally if youre talking about a signal pattern, youre working with rms V, I, W

dbi describes antenna radiation
dbm describes power vs a mw
but right sounds like you have the general idea
higher dbi means its more focused, more directional
so 1km range is maybe shooting a narrow beam
but im not an rf person so none of these proportions are intuitive to me
no
it told you 95mA at 0 dbm
thats 95mA for 1mW

so its ratio of power at a point versus a spherical radiation pattern

its dB referencing mW
10dB is 10x
so 20dB is 100x, so 100mW
dbi is less obvious, dunno
for volts its 20x
er no
for volts, 20dB is 10x
im not an RF guy
but right i think it has to do with focus of the antenna
sec
In electromagnetics, an antenna's power gain or simply gain is a key performance number which combines the antenna's directivity and electrical efficiency.
Antenna gain is usually defined as the ratio of the power produced by the antenna from a far-field source on the antenna's beam axis to the power produced by a hypothetical lossless isotropic antenna, which is equally sensitive to signals from all directions.
