Hi,
I am thinking about going wireless at my kids' condo.
One is iBook located in the loft, one is PC notebook
on the main floor directly down below. Would I have any problem
with signal quality? Anyone has set up like this?
About 40 feet vertical distance at the most.
TIA,
Tony

I struggled to get a useable signal 40' away horizontally, until I read
a post saying that the ABS radiated in the plane of its base. Mine was
mounted on the wall with the supplied bracket, so the radiation plane
was vertical. I took it off the wall and set it flat on a bookshelf
and more than doubled the signal strength 40' away horizontally. My
experience suggests that if you mount the ABS on the wall so that the
radiation pattern is vertical, you will be fine. Burt

There is usually a dead zone in the direction in which a simple
"rubber duckie" antenna is pointing, as macbum learned.

Hi,
Makes sense. Dipole antenna has figure 8 radiation pattern.
