My question is: Can the wire be used *with* the loop also? I was thinking
of hooking the run of wire to the loop. Will this work? Is there another
combo with the antennas I used for the BCB that I can use to squeeze a
little more?


I am confused as to how you are coupling the loops to your radio?

Are you using a communications receiver or a portable? Are you coupling a
tuned loop with only the primary winding to a portable via inductive
coupling and rotating the pair on a lazy susan?

Yes, a loop can be phased against a long wire or beverage/BOG type antennas.

A loop used for phasing against another antenna must be a broadband loop,
usually an amplified untuned loop or a Q-spoiled loop. The sharpness of the
traditional box loop's tuning causes a gain change across it's passband
that makes it impossible to use the effects of the phaser to properly
cancel out the target signal you are trying to eliminate. Because of the
high Q of the box loop, the gain across the narrow passband is not uniform.
This causes the phaser to null out the carrier of the target station and
not fully null the sidebands, leaving the Donald-Duck sound of an SSB
signal remaining.

Q-spoiling on the loop eliminates this issue at a slight penalty in
sensitivity.

Some commercial ferrite loops have a switch to broaden the tuning to allow
correct operation with a phaser.
