Cubex Quads recommends 1/4 wavelength 75 Ohm matching sections for each
band. Might need 3/4 for the 10m driven depending how far from the relay
box. So does this NCJ article. ncjweb.com/features/janfeb08feat.pdf

Dan,
Many thanks. That pretty much says what I wanted to know (and a whole
lot more!)
It seems to me that a just reach length, or rather some arbitrary length
close to that is going to be the best compromise.

The pentaband quad in the ARRL antenna book has had a couple of
recommendations as a good design based on my web reading and it
makes an interesting point with regard to the feeding method.
There is a very detailed study of the feed system for the ARRL
pentaband quad in the 5th section of this page:
