Hi All,
I have an 18db parabolic antenna pointed at a Tin Cantenna about 800 metres
away line of sight.
From the netcard at the cantenna side, I'm getting 40% signal strength. My
access point rarely sees the cantenna however and generally not for very
long.
I've heard the antenna gain is same for send and receive so I take it that
my home made cantenna should be sending something out. Could it be that the
parabolic antenna sends in a wider arc which the cantenna can see but not
vice versa?
There are some tall trees to the immediate right of the line but I can see
the antenna clearly. I've read a little about the "Fersnal zone" and that
you shouldn't point the antennas directly at each other. Could this be
causing dramas?
Thanks for any input.
