Are there any websites that give the polarization for TV signals?

For the US, the FCC database tells the polarization (elliptical is
pretty common.. mostly horizontal, with some vertical component)

For instance, here's the stuff for KCBS-TV in the Los Angeles area:http://fjallfoss.fcc.gov/cgi-bin/ws....cc/prod/eng_tv....

Horizontal pol

But channel 11, KTTVhttp://fjallfoss.fcc.gov/cgi-bin/ws.exe/prod/cdbs/pubacc/prod/eng_tv....
has Elliptical..

The search page is hehttp://fjallfoss.fcc.gov/prod/cdbs/p...d/sta_sear.htm

Concerning a TV station using elliptical polarization is there a
purposeful phase difference between the horizontal and vertical fields
or is it simply just dividing power between horizontal and verical
radiators with no concern as to phase relationship
