Use 3.3 with a loss tangent of .008 @ 10 GHz as a good average. LCP is
all over the place and actual local Er depends on how much glass is
contained in any section of the extrusion. Thiner sections contain less
glass. Thicker sections are closer to the 30% average loading for this
material. You'll find that loss tangent for these connectors does not
much matter.
