read it where?

Given how TCAS II works, it doesn't make sense that a head-on encounter
wouldn't work well, even at cruise speeds.

Have you ever talked to anyone that was involved in flight testing of
TCAS II?

If I knew, I would have gone back and quoted it, here! g That is kinda' like
trying to look up how to spell a wierd word in a dictionary. How do you look up
how to spell it, if you don't know how to spell it? ;-)

I think it was on one of the aviation newsletters that I get on a subscription
basis. AvWeb, perhaps?

Could be the high closing speeds, the radiation paterns of the antenna, or
something. I don't have any more details.

Nope. Like I said, I only heard (or read) it, and posted it as a very "iffy",
possible-maybe-could be it-explanation.

Not very definitive, don't you think? g
