Let's be clear. There is absolutely no problem building a very wide range antenna 'tuner' that can handle kilowatts of RF at an SWR of 10:1 or even much higher.
Such a tuner is very easily fabricated, but requires physical space with large switches to avoid corona discharges and uses big air-wound coils and large wide-spaced transmitting type variable capacitors to work efficiently. It's the demand for a "compact, fast QSY" system that poses the huge engineering problems. And that's why the most popular Ham antenna systems (including tuners) are the most popular. They aren't necessarily the most cost effective or the most efficient. What they do that makes them popular is they are a decent tradeoff between the power handling and rapid QSY capabilities many Hams today demand. Those of us who don't insist on that "compact system, fast QSY" capability have an easy life, Hi! 73, Ron AC7AC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
