I tried combining two HDB91Xs together, and the performance did not really improve, infact, it gets a little worse. Questions on this:

1) How close to "exactly the same length" do the feed lines need to be. I'm using two 3-foot lenghts, and they vary by about 1/4". Is this too much?

2) Will it be worth fiddling with the separation? I tried 39" as a first cut, per Tigerbangs suggestion.

3) I'm guessing the antennas also need to be "perfectly parallel". Its kind of hard to ensure this exactly unless I add another cross-piece. Seems like this might be worthwhile. Thoughts?

Thanks guys!
