Hi Chaz, My thought is that concern over the simulated antenna can be neglected if the the source is "electrically short dipole" at the frequency of interest.  Simulating with the radiated field from such a source, with and without the shield, at a far field distance, should give you a decent

I suggest that a suitable source for evaluating the shielding effectiveness of a BLS is a multivibrator (square-wave source), with attention to rise and fall times: not too slow and not ridiculously fast. It's more representative of emitting sources than a canned antenna. =
