It really depends on the equipment.
Most higher power cards do not have a very good receive sensativity, and
in general lower power cards do. However a higher gain dish can pick up
more noise aswell.
If you're trying for a long distance point to point link, i'd go with a
higher gain narrow beamwidth antenna and a low power radio.
If I was setting up an AP and wanted reasonable coverage from an Omni,
I'd probably go for a higher powered card (maybe 100 mW, to still have
Depending on conditions, the 15 dBm/20 dBi combo should get you around
15 to 20 Km's or so anyway, with a good frenzel zone and line of site.
