70cm Quad?

[KB3THX]

Good Day,

I am trying to find an old article I once had on home-brewing a 70cm quad using PVC pipe boom, and wooden dowels as crossbeams for copper wire elements.  Does this ring a bell to anyone?  I've searched the web for a few hours and cannot find this how-to article.

If anyone has the article or a link to it, your help would be much appreciated - thanks!

You seem to recall the important parts - using a PVC boom and dowel spreaders.
What do you still need?

I've built several quads using W4RNL's dimensions here:

There is also an online calculator using his equations somewhere, but I found an error
in one of the element spacing dimensions.

One was a 4-element design for 465 MHz using the same construction method that
I threw together quickly for some DF work, and it had a great pattern without any
length adjustments.  Because I was in a hurry I soldered the loops into squares and
tied them to the sides of the spreaders with plastic strips.  It would have helped if
I had secured the spreaders better to the boom, however, as they tend to slip around.

Post Pictures it will be cute.
I made a 70 cm hex, it looked like a toy but worked very well.
The spreaders were very light fiberglass on mine, with a UHMW center hub
