Dean,
 
One antenna is fine if you consider the need to have a switching box so that engaging the ptt button does not allow the hi-powered transmission comm signal to reach the other radio.  When not transmitting, the switch allows reception on both radios.

I was looking for some advice about communication antennas.  The 
legacy is setup to have one com antenna.  We want a capable IFR 
airplane and I am hesitant to have one antenna with a diplexer (or is 
it duplexer, I've seen it both ways) as a possible single point of 
failure.  Is this the method that most people are using?  If you 
mounted a 2nd com antenna, where did you place it?  I searched the 
archives and found someone else who asked the same question but I 
couldn't find the answer.  Any other input or advice on the subject 
would be appreciated.
