My QFH antenna project

[2sudsy]

This is a powerpoint presentation of a quadrifilar helix antenna for 136 mhz. I built it from parts at my local hardware store. https://dl.dropboxusercontent.com/u/83615241/quadrifilar helix.ppt

OK ? Ether no one is interested in a 136 Mhz satellite antenna which works just as well as a high gain scanner antenna or maybe no one is able to view PowerPoint. If PowerPoint is the problem, I apologize. Here's the slides in good old fashioned JPG format.

Seems like a lot of effort for weather bird signals.

Yes!......A lot of effort.............BUT.

I've noticed that the satellites do come in without the usual slow fading. So the antenna does work as claimed.
