1 45 Watts 4 Element Yagi Horizontal 100 Degrees


Three hunt teams showed up to find us on Cliff Place at the north end of Normal Heights. This site was selected to take advantage of the naturally occurring RF reflections we have all grown to love in the Mission Valley corridor. Tony and I configured our hunt vehicle as the drive up transmitter since the selected site had little opportunity to set up a stand-alone beacon. Initial transmissions were set at the five watt level through a four element yagi. After about 15 minutes into the hunt, the RF power during each transmission was randomly alternated between five and 40 watts to add a bit of a challenge to the hunt. Finally, the yagi antenna was rotated slowly during transmissions to throw some additional confusion into the apparent signal bearing. As expected, the arriving teams reported some difficulty with getting trustworthy bearings, which resulted in quite a spread of total hunt times. My compliments to the hunters for using their skills in hunting this "Pandora's Box" style signal.
