In a wardriving application, which would be better:

1. An omnidirectional magnetic-mount antenna such as the one at
http://www.fab-corp.com/I1.htm
2. A homemade coffee-can mounted perpendicular to the vehicle for signals
coming from one side.

Obviously #2 would only pick up 1/2 of the potential signals but I thought
the power of the antenna might compensate by being pretty reliable at
picking up what's out there. I'm not sure how well the 5.5 dBi would work.
Anyone care to comment?

24 dBi grid parabolic on a constantly rotating antenna mount!!!. Oh
well jokes over. My suggestion is a high gain omni of about 9 dBi
gain. Anything higher and the beamwidth is too narrow.
