Same thing, two different ways of saying it, and very true!

About time someone wrote an article on the design of a lowpass
filter for a single band capable of handling 1500 watts
continuously, 50 ohms, to allow a transmitter to meet all of the
various regulatory agencies' specs, cheap, easy and quick to
build using parts commonly available, with little test equipment.
