Blue System: PreAmp & Antenna Questions

I'm on the last legs of setting up my Blue system and have some questions.

1) On the pre-amp board are the connectors A-1,A-2 and B-1,B-2 relate to the vertical antennas?
2) On the pre-amp board is the connector C-1,C-2 for the optional horizontal antenna?
3) I intend to use my loop antenna I had on my Green system, Which I was under the impression it did not matter which way it pointed, is this still so?
4) On the Green system the loop antenna windings were wound in a certain direction, and had to be wired up to the Green pre-amp the correct way, is this still so for the Blue system, if so which end of the loop goes to which connector (1, 2) ?

1) Yes.
2) Yes.

I'm unfamiliar with the Green system.

3) If that "loop antenna" is two loops at 90 degress to each other the combination is omni-directional. If it is a single loop that has a figure of eight polar pattern and some thought in it's algnment is required.
4) Polarity doesn't matter on Blue, though if you construct and wire it so you know which quadrant results in the same polarity signal from each loop you can get a vague indication in direction from the polarities.
Cheers
Dave.
