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. Dean Whiting
