I have built helix antennas from the sites of G6LVB and N4WYK all with PVC.
Here are some good websites for 2.4GHz helix antennas.
Click on satellite website, then click on "2401MHz Helix" above the picture of the antenna.
Select 2.4 GHz helix.
Select quadruple helix for AO-40.
A site for good reading and links.
There are advantages and disadvantages to each type, dish, yagi, or a helix antenna.
If I can be of any help, please email me.
