Final Notes:
Horizontal shows a little bit a flare just off axis in the 7-8k range but that evens out as you move further to the side. Overall the horizontal is fairly consistent around 90 degrees before starting to narrow as you go above 7 kHz. Vertical coverage is a little more uneven though not terrible with some waist-banding centered around 4-4.5kHz developing into some other dips further off axis.
