[Novalug] problem getting wifi signal

[Jason Kohles]

People routinely get signals 2-3 km with nothing but a homemade waveguide (google for cantenna or wifi wok for examples.

The important thing to remember is that the signal is bidirectional, if you are going to use a high gain antenna for extra power, you need to do it at both ends of the link.

I remember some years back about groups building their own antennas.  You
might google this stream and see if it digs anything up.
