ISTR that the essence of maintaining a balanced (to earth) arrangement is that by so doing you maximize the depth of the null. The polar diagram for max. signal may also become asymmetrical if the balance is upset.
And, just for what it's worth, I recall that many years ago, I discovered that common twin flex (such as what you are using) has a Zo in the vicinity of 75Ω.
