Hi Tom!I had overlooked a couple of your statements earlier, because it seemed that other points were more relevant. The discussion of radio waves and UHF was not really the focus of our discussion, but it does serve to illuminate a point.

The horn system unloads at a relatively low frequency because of the motor's mass. To describe a system with an impossible part is somewhat irrelevant. It is to discuss a "widget," and to compare this with actual devices is pointless.

I've used conical horns for audio for over 20 years. And you're right that it is a shape that is commonly used for RF. Of course, radio travels at the speed of light, or 670 million miles per hour compared with sound, which is only about 770 miles per hour. The difference in scale is huge, so a horn the size of the Unity or other midrange horns could not be used efficiently for RF under 100Mhz.
