What are your requirements or what are you trying to accomplish?
What does the area of intended coverage look like?
Do you need it for something like a point-to-point bridge or general omni type of access?
I need a Omi Directional antenna trying to pickup a signal 1/2 to 3/4 away
An actual measurement unit would help here.
What is 1/2 3/4? Are these miles? Kilometers? Light years?

You aren't going to find a great omnidirectional antenna that is designed for that kind of range, when you get into miles or kilometers you're looking at directional dishes. If you need WiFi coverage over this distance, you should really look at getting a point-to-point transceiver on both ends, such as this:

My post still applies.1/2 to 3/4 of a mile sorry I did not say that
WiFi needs a direct line of site in order to work over distances, if there are houses and trees in between there's not much you can do.There are some houses 1 story and trees inbetween
You'd need that on both sides. My feeling is the OP wants to use someone elses WiFi but doesn't have access to anything on the other end.Could you mount that antenna higher then the stuff in the way? Also, running a lot of cable will impede the signal and you need to use some thick stuff like LMR400. http://www.simplewifi.com/400/
Here's an antenna that would work. http://www.simplewifi.com/long-range-20dbi-panel-with-18-beamwidth.html
I've seen those used at the golf course over here.
