Thanks for the replies guys.
Roger - OK on the Pawsey stub. I've seen many iterations of this, usually it involves the 1/4 stub connecting across the feedpoint and shorting out to the braid of the coax, not the boom. I assume the same effect will be had with shorting to the boom, as long as the 1/4 piece is electrically the right length.
Jayson - OK on the ferrites... I've already sealed with collar tape the other three further down
. I'll post a photo here if I can figure that out... I just didn't want the toroids drooping down within the elements, as you'll see from the photo...... here.

Last photo is upside down which is annoying, but I think you get the idea.
I do have more ferrite cores, I was saving some for my 6 metre yagi, but I'll probably need heaps more and there is better ways to do that.
So, if I cut the collar tape on those other four, and place them hard up against the first one, best practice?
Is it also better to do the 1/4 stub, limited bandwidth (could be a good thing?) or just screw the middle of the far end of the driven element loop to the boom?
