90 deg antenna design needed

[Chris King]

Hi,

I am planning to put up a community access point as part of www.e3.com.au. What I need is a design for a 90 deg antenna. Has anyone seen a page with such a design? Failing that I have an idea detailed at www.iinet.net.au/~hascom/WaFreeNet/HillsHub.html and would be very grateful if anyone with any antenna design knowledge would care to comment on it.

Thanks,
Chris
