The cap is in the middle coupling the coax center conductor to the top wire Eddie,
the stub is part way down the coax, its placement & value are important,

when you get it right you should see a double dip in the vswr curve as seen in other antennas using coupling capacitor to help with broadbanding such as the the x-pole,

unfortunately for us the highest vswr point between the 2 dips is around our ch19,
that could be why the gain-master won't handle anything close to what sirio claim continuously for us,

the idea about 3 wires where i only see 1 is from what you say above and my interpretation of the eznec manual.
