yes, i agree. But I think I have to clarify what I acutally meant:

_given_ that many freifunk/funkfeuer/cuwin meshes are like they are now,
and _given_ that our projects attract media attention and therefore - as
it happend in VIE now - the attention of the (local) FCC
("funkueberwachung", "regulierungsbehoerde" in germany) and _given_ that
- as you are all freaks - you installed high gain antennas. 
THEN not everything is lost. You can still use these nice 24dBi high
gain antennas on the manner i described before.

In VIE we recently faced the problem that our main uplink was
transporting bandwidth into the mesh via 24dBi antennas (which as TX
antennas are to strong). We had to take them down and replaced them with
"legal" less powerful antennas. 
Only to find out now that the Diversity dissociation loss on the linksys
seems to be 26dB. Voila! We could have kept them there and just add a
small antenna on the TX side. :)

That was my point 
Hm, and did I mention that you can switch RX and TX side in
software ? ;-))

agreed agreed agreed. But IMHO the full MIMO phased array multichannel
solution for 60 dollars does not exist yet. If so, please tell me where
I can get one :)))
