Outernet , possible alternative for Iridium or SSB weather ?
a couple of weeks ago i wrote:
"THE CHALLENGING PART is to make an antenna that can and will recieve the signal with the boat in movement, make the whole system in the way that is drawing power as low as possible, while recieving, and last but not liest make it waterproof and EASY INSTALL that way annyone can install it with no problems onboard.
The past days I'm gathering pieces and setup test ambients to make an omnidirectional antenna suitable for recieving outernet.
Since is working on relatively high frecvencyes i had to rent somme pieces of test equipament nedded for testing and building such antenna and still waiting for couple of bit and pieces for the antenna.
I'll keep you posted on how the tests are going and what results I've came with.
the goal is to make an antenna that cost under 150usd (one inmarsat L band antenna that could work is around 700usd) and an autonomus system under 300usd everything included.
Like outernet everythig is open source and who has the time and will to help is welcome, soon will be an online project
site dedicated to this topic."
wee tryed the patch antennas onboard but with the movement is not a suitable alternative, the dish is out of discussion and the gps antennas do not work well in this case (for those that do not know the gps system has always at liest 4 satellites in sight overhead and the signal is much stronger than outernet)
UPDATE: We managed to have a decent signal on our antenna with no amplification at all, and now waiting for the high frecvency parts
to start with the first circuit boards for testing... the antenna will have no moving parts
and it's almost omnidirectional...
