A better spacing is 1/8 wave or slightly more (about 8-10 feet on 20M). A
properly tuned 2-element quad or delta loop beam has close to 50 ohms feedpoint
impedance. If you change the spacing and the SWR gets closer to 1:1, that's one
indication that the antenna is working.

idea to add an element to my 20M delta loop. I got the thing up for a while
Saturday, but I really don't know if I have gained anything besides that "look"
from the XYL. You know that "look." You've seen it - you've earned it, too!

is there any on-air or poor man's test that can be performed to check if I am
getting the expected performance gain? I did get an on-air SWR of about 1.6:1,
but I already had that with the single element. Electrically, I'm spacing the
elements 3/8 wave apart and the feedpoint is about 30 feet up. Any suggestions
would be greatly appreciated. If this doesn't work, I'm only out $20 in PVC and
dowel rods, so it's no great loss.
