Final Notes:

The exponential design of the horn results in some narrowing of the pattern as frequencies increase therefor difficult to give a single number for the dispersion, but the rated 90x40 seems roughly close to spec, or perhaps it measures a bit wider horizontally depending on where you choose to define the angle.
