Getting really close to having everything installed and working on the roof! May get to work some birds later today if the XYL doesn't corner me with housekeeping chores in preparation for tomorrow.
One of the antennas that I'm putting up is an old Cushcraft 30 element 440 with a polarity switch. I have not been able to find any documentation on this antenna and I wonder if there is an easy way to determine if the antenna is set up for RHCP or LHCP. Clearly feeding 12v to the switch will change the polarity but I'm wondering if there is an easy way to determine what the default setting is before the switch is energized.
