2.8 Coverage
W8CT and W8CMs are designed to be flown in vertical line arrays to provide a
combination of W8C-compatible 55º horizontal coverage with tight vertical control.
The vertical coverage of a single W8CT is approximately 7.5º in the upper midrange.
When dead-hung, as illustrated below, the vertical coverage narrows with increasing
cluster height following the classic law for multi-element line arrays.
* = speed of sound (m/s).Varies with temp. (see Section 2a)
Arcsin = "the angle whose sin is..."
(Note that Nd works out to be the total height of the column in meters)
