[Discuss] Antenna Signal Issues

[jack at coats.org (Jack Coats)]

In a wifi setup I have, I found it helped greatly to get a flat pannel
antenna.  It is directional, but 180 degrees not a 'beam'.  Still, it
helped boost reception for my situation.  The antenna generates a cardioid
pattern, so most of the 'active area' is out front and little behind.

Basically anywhere mostly in front of the antenna I got better
reception/transimission.
