from.
For better pinpoint accuracy and even greater range, use the cantenna
as a feedhorn for a TV dish antenna.
Something that might be handy for war-dishing is software that can take
a video feed from a cammera being panned and tilted with the dish and
composite it into a panoramic view with the kismac signals
superimposed..
Also, you usually cannot send signals as far as you can receive them.
In
other words, you may be able to sniff traffic from an AP, yet not join
the
network.
This would mostly be because KisMac is ignoring most data errors while
in promiscuous mode. An access point will ignore the whole data frame
if it isn't error free. Another factor is that a directional antenna
can reduce the noise level seen by your receiver but the AP's
omnidirectional antenna is picking up noise from all around.
