Oh, I forgot...circular polarization would be excellent to use on VHF and UHF 
repeater.  We want the extra signal strength & the multipath would be way less; 
less deviation 5 kHz vs. 75 kHz means less susceptability to multipath.  
Pasternak's Repeater Handbook shows actual results.

                  In reference to below, what would be the real advantage to 
using CP antennas in addition to the V and H you'd have already?  Any signal 
that arrives will excite a V and/or H antenna according to it's arriving 
polarization, and I don't see where CP would be a help.



Most FM broadcasters use CP.  Those that don't are licensed for only V or H or 
choose to use a less-expensive single-polarization antenna.  And many of them 
look like rototillers, and other shapes.
