Here are some of the members of the Pasadena Amateur Radio Club, JPL ARC, and Caltech ARC setting up their antennas. The beam show here has 2 elements on 10, 15, and 20 meters. Coming down from the pole on top is a 80/40 meter dipole, built just prior to field day.
The JPL and Caltch clubs combined their efforts to provide this CW station to the Pasadena ARC field day in a joint FD effort. We got the antenna up, but the dipole was too close to the pole, and one of the separation insulators came lose. Fortunately, there were enough engineers on hand to resolve the problem.
Setup started a 7 AM. After the antenna issue was resolved and a minor computer setup item was fixed, the station was on the air within minutes of the contest starting.
