[amsat-bb] Polarity Switch Question

[David Wing]

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.

 

73, David
