Years ago before CP antennas were commonly available, FM stations would feed 
two separate antennas on the tower.  One was H, the other V. Was that then 45 
degree polarization??

The local channel 8 analog station here had a CP antenna.  To get their 316KW 
horizontal ERP they put 77KW up the coax from a many-yards-long Larcan 
transmitter.  They had a whopper signal around here and it was very easy to get 
a great picture even with rabbit ears.  I know that their excellent signal 
wasn't just because of CP, but it had to help.  I wonder what their reasons 
were to go CP?
