Final Notes:
Horizontal is fairly even until the top octave where it begins to narrow. Overall coverage angle appears slightly less then the rated 90 degrees through this is a clone and it might not have the exact same shape as an original HF101. Vertical is also somewhat consistent with just a bit of narrowing in the 9-14khz range, the overall rating of 60 degrees is about right for that axis.
