1The two halves of the 144MHz bidirectional beams were not tuned to the same frequency, nor to the test frequency, resulting in measurement at two different points on their respective gain curves. Measured at the gain peak, they delivered 5.94 Dbd.
2Antenna was resonant above the test frequency.

2 The 432 MHz range was plagued with reflections which affected accuracy, especially of low-gain antennas. Rain and thunderstorms precluded further tests that might have improved accuracy.
