Well, the wrts have already been bought but I have a couple from tmobile
with 32mb ram and heat sinks.  Well, I already have a ton of cantennas and
I was interested in building biquads.

So you suggest 4 outside routers at the gateway location each pointed in a
different direction?

There is almost no other wifi activity in the air.  We're building
birdhouses to protect the routers with computer fans on the bottom that
will be solar powered to cool in the heat.
