They are designed to transmit things sideways - not up or down. So there is no signal at all if you get higher up than a couple of hundred meters.<br>
<br>And there will be a similar problem with any form of communication device youll put on it. Unless you want to umph out several hundred watts of signal you will need to limit to where the signal is sent to either straight sideways or directly down.<br>
You will also need to pick a form of communication where the one youre communicating with has enough power to get the signal back to the balloon. (Its possible to set up a WLAN and add an (illegal) amplifier to it to make the signal reach the ground. But unless you got a very large (and heavy) antenna to receive the signal from your users it wont reach the balloon.<br>

</div></div>I like the idea of testing the "site" separate, perhaps on a boat....<br>
Is this something you have the know-how on?<br>
<br>
In that case, I think that by just syncing on what the contraints will<br>
be - its probably just a matter of getting things done on it.<br>
<br>
I'll have some preliminary discussions over a coffe with a friend here<br>
in Sweden and I think we can start up some basic things.<br>
<br>
Input needed on communications. Is it difficult to get comms working<br>
on altitudes?<br>
