Hi!
I'm glad to know that someone already did what I'm planning :-)
Hope you don't bother to comment your experience a bit more:
- did you set the RGs to 1/2, 5.5 or 11Mbits?
- do you recall which were the ping averages while getting
the 140KB/sec http transfer?
- english isn't my primary language. Do you mind explain me what
low "fade margin" means?
- I thought the ocean would cause more reflection than
a link over the ground!!
- good to know it survived a storm. on the 660m location, it
rains a lot!!
- I was told that 1.5 meters solid parabolic would be rougly
equal to a 3 meters grid antennae. I'm not sure it is true, but
that should help -- plus the 6dB margin from my 31dBi antennae
to the 25dBi ones you used ;-)
- solar powered? nice! did you buy it ready or did it yourself?
did you considered eholic power?
- how did you align that antennaes? GPS? "by-hand" (ping open
and checking the signal report for each RG-1000 through the
config utility)? We never did something so long before!
Thanks for the input!
Cheers
