- Don, there is height of 31.5ft but electrically radiator is longer than that, even longer than it should be so the series capacitor is in line with radiator. So there is no way you can make assumptio

- Not with just "any network analyzer", like the 8711; you need a 4 port network analyzer, such at the Agilent E5071C with 4 port option. I've measured many baluns with one of those. Gives common mode

- You should fixture the balun under test on a ground plane with 4 connectors grounded to that plane. The 4 analyzer cables go to these connectors. You don't connect anything from the DUT to the groun
