Yes, I had to go back and search to be sure I really saw it there.

Horizontal beamwidth is technically defined as the "Half-Power Beam Width (HPBW)". This is the arc that covers the peak lobe and defines where the reception is 1/2 the peak on either side of maximum, also known as the -3 dB points. A good tutorial is available at http://www.antenna-theory.com/basics/radPatDefs.php

Thank you that is helpful

Should you need the wide BW of a C4 but desire a bit more gain, you can stack two C2s vertically on the same mast and combine them with a reversed splitter and two equal length coax segments...

Interesting... just to be clear you mean "...the wide BW of a C2 (not C4)..." correct? In any event I think I would do better just going with a DB4e which is >similar< (by my understanding) to a pair of C2s stacked.
Thanks again, your input is always helpful
