Check out Rc-explorer's guide on how to make these antennas.
This jig helps you keep it 120 or 90 degrees depending on if you are making a 3 or 4 leaf antenna. The walls are 45 degrees so you can choose if you want to make RHCP or LHCP antennas.
These antennas where invented by IBCrazy from the rcgroups, and are excellent on FPV use for video transmissions.
Follow the guide on rc explorer on how to make the leafs match your frequency, and place the leafs in the jig an solder up.
The guide for the antenna is here: http://rcexplorer.se/page14/CPantennas/CL/CL.html

Note: This does not work with 900mhz, if you plan to use this with 900mhz you need to add some support on the 45 degree walls for added length.
