Please note that a basic vhf swr meter is needed to trim the quarterwave stub. You will get the vswr down to 1.1:1 quite easily.

You need following items:

4 electrical conducts. 25mm white pvc pipes.
RG-8/213 to carry the vhf signal.

1x reflector
1x driver, quarter wave 75ohm coax, rg213 feed.
1x director 1.
1x director 2.
2x director 3,4 (these are same dimensions are director 2) if you intend to make it into 6 element.

My experience on hf and vhf. 4 elements are tremendously powerful and you can do lot more vs yagi. Only downside with hf is the 3 dimensional model which makes it tricky.

For 40m etc, what i did was to use delta structures and have a single boom. Off the boom I had these 2 elements come off as a driver and reflector spread out using nylon strings. It worked very well.

Quads are just great and very forgiving. If you live in areas where aluminium tubings are an issue; then quads are the way to go. Trust me, you will not go wrong with them.
