Erratic results

I am simulating some equal delay Ruthroff transformers using Momentum. The results are as expected up to the point where the transformer is half a wavelength long but at higher frequencies the results are erratic and seem to alternate between high insertion losses of around -10dB and gains of up to 5 dB.

This completely goes against the theory of equal delay Ruthroff transformers and I can't think why.

The same problem also occurs with Guanella baluns.
