Last time I checked (and I'm going from memory), there were high power
access points that put out 20-25dBa, instead of the 8-12dBa that is
standard (that's 500mW, instead of around 18mW).
There are also commercial directional antennas, such as Yagi and
backfire antennas, with gains of up to 16dBi. But, as Jason said, there
is a need for them to be line-of-sight. If that's not possible, you may
need an antenna with circular polarisation - these are more expensive.
But most are not suited for dual frequency signals (and in any event you
probably won't get a 5MHz signal to propagate 500m).
Of course, you should plan on two matched antennas.

Hi Sluggers,
I have a friend living in near jungle conditions in a small town
in the Philipines that wishes to span about 400m - 500m from
an Internet connection to his house in the bush.
Ethernet seems limited to 100m.
Wifi seems limited to about 100m - 200m.
Any suggestions for bridging this gap?
thanks,
