Best coax for aircraft radios

Sorry that you think this is a marketing ploy. I thought that this was
a forum for information exchange. I just wanted to pass along my
experiences working with all kinds of coax under a lot of extreme
conditions, and the lessons learned from them.
As far as the props, If you had designed a prop that gave performance
so far beyond the others available and this performance was
demonstrated in the best way, wouldn't you want to share that with
others? I don't sell cables or props or ignitions; I leave that to
others. I guess there are some of you who don't care that there is a
revolution in prop design that can give you markedly better
performance. Or coax that will up your radio's performance. Perhaps you
don't also want me to share with you the research I and another have
done to keep your prop bolts tensioned regardless of temperature or
humidity. When all you do is put down others who want to share, you can
suppress that sharing!
