Cough! Splutter! Spits coffee all over the shack!

$2000 for a 1mbit link! Get real. We just put up a 2.4GHz wifi link on
our tower for a 2.5 mile link to our Internet donor for change of $200
and that included a new box of Cat5 from Home Depot.

I'm not saying that one can do quite as good as that all the time but
you can certainly do it for change of $500. OK, so it's in the 2.4GHz
mess but we have yet to see that be a real problem.

None of it was cludged. It was all proper masthead routers with POE etc.
We just took our time shopping on ebay and were able to collect both
ends for a reasonable price. We have a an alleged 54mbps link but I
think the throughput is more like 20mbps. Hard to tell really. Both ends
report a signal of "65" on a scale of 1-100 where 100 is the best. Not
exactly scientific but good enough for us to peak the signals/beam angles.
