It is important to remember that it is not really triband wires, but
tribander SINGLE ELEMENT. I think (my opinion) that it was a huge
mistake to nickname it TB Wires because a lot of efficient antennas
can be made from wires. But anyway it is tribander single element.
So the guys with v beams wire beams etc would not qualify for the TS category.
In my opinion Warc band antennas are irrelevant because we don't
contest on the warc bands so it gives zero advantage during the
contest. If warc band antennas were disqualified the guys with
steppirs, verticals or even g5rv's would be in a pickle because they
wouldn't qualify for TB Single since those antennas are "all band"
antennas and not triband antennas.
Remember the intent of the category - to give a typical single tower
home station a shot at winning amongst the big guns with stacks of
beams, four squares etc.
