I got a chuckle out of Jim's comment. My two A4S trapped tribanders for
field day NEVER went together correctly the first try - one tuned for CW
the other SSB. Fortunately, the Will-Burt pneumatic mast made it easier
to try again.

I suppose I can imagine a field day scenario where someone
had marked all the elements with tape or paint (1 band for director, 2
for driven, 3 for reflector, different colors for different bands) and
the tape fell off or paint faded.
W6VIO (JPLARC) field day more than a decade ago, and someone has the C3
all bundled together, with no instructions, and we're trying to figure
out which element goes into which hole. Someone in the past had marked
it in the past, but the markings were only on some elements, and we
couldn't figure out the pattern. I don't recall how we figured it out.
Maybe someone looked at it after we got it together and said "well, that
looks like how I remember it". At least we knew it was an interlaced
design, so you could group the elements by band using their length.
It did work, but one never knows in these situations - if propagation is
good, and for field day, it's more about "how many people are in the
zone of propagation" than raw antenna gain or F/B. That is, you could
probably do about as well with a dipole, if you're on top of mountain in
California - it's not like F/B makes much difference when there's nobody
to the west of you and you're pointing east.
