Again, watch out when making generalities!

An untuned antenna is a mystery at best. Just because it isn't resonant on a spur frequency means nothing. In fact, it could exacerbate the problem. You'd have to very carefully characterize the antenna to be able to make such comments. NEVER, NEVER depend on an antenna system (antenna, tuner, feedlines, location, etc., etc.) for harmonic/spur suppression! The ONLY right way is to eliminate them (meaning suppress them as best as possible) AT THE SOURCE, namely the rig.
