I just returned from a week family leave; sorry for the delay in 
answering your questions.

Here's the polarization definitions we've been following, provided the 
dipoles are orthogonal to the apex quadrapod legs:

LCP = XLP ("X" Linear Polarization) which is the axis parallel to the 
ELEVATION or HORIZONTAL axis.  The old legacy 74 MHz system often 
referred to this as the North-South axis (which I've never quite figured 
out the genesis of this, as this changes from arm to arm, never mind 
azimuth pointing).

RCP = YLP ("Y" Linear Polarization) is the VERTICAL axis when the 
antenna is pointed to the zenith.  The quadrapod leg with the ladder to 
the Apex also defines the VERTICAL axis.  The old 74 MHz E-W axis.

Thus,
R = Vertical
L = Horizontal

I am attaching an Appendix to the LBR Technical Manual (under 
construction) that illustrates the various polarization axes.

If there is any dispute with these definitions, please let me know.

Paul
