Re: long distance LAN

I have an associate here in Illinois that purchased a microwave type system
that does 10mbps and then could not get the building permits for the tower
at one end.  The requirement was if the tower fell, it stays on the
property.  There was a ridge in between the two sites and he needed about
100 ft at one site.  But a 1/4 mile should be no problem for this type of
system.  It uses an antenna that looked like some old wireframe parabolic
dish.
