Hi

Larger is better. I have a K9AY 50% higher and wider. Better signal on 160/80m !

Don't forget to make four wires on the ground connected to shield to ground on the box..

I don't think I've ever read anything about this.  Just rechecked the Array Solutions manual and found nothing.  Reason for asking is that I have to replace my fiberglass mast, and while the old one was about 25 feet tall, the new one is 31.  That raises the possibility that I can put the bottom of the loops 5 feet higher, or change the shape of the loops, which currently have their bottom legs more or less parallel to the ground.

Diagrams I have seen generally show included angles at the outer points of each loop to  be well under 90 degrees, and the lower segments almost parallel to the ground.  Has anyone experimented with this? What about the usual shape, but higher off the ground? I have 4X30' radials plus a ground rod, with the radials laid under and in line with the elements
