If the pattern in the spec sheet is accurate, this one looks like it's actually a bit more than 120 at -3db http://www.streakwave.com/itemdesc.asp?ic=HW-SA58-120-16D&eq=&Tp=&o1=0
These also look to be a full 120 at -3db http://www.streakwave.com/itemdesc.asp?ic=SA4958-120-19-D&eq=&Tp=&o1=0 On Wed, Feb 18, 2015 at 11:54 AM, Jerry Richardson <[email protected]> wrote: > You are right, there’s a little note that says 120* is -6dB.
