Salem at least owns the towers, if not the underlying land. The towers 
are registered to "Pennsylvania Media Associates" (a Salem shell 
company) at Salem's Camarillo, CA address.

address in Georgetown, TX. I don't know who that really is.

Clear Channel does own the 1430/1090 site. It would not be necessary to 
diplex 1090 and 1030, however. 1090 uses only one of the two towers in 
the array, after all, so 1030 could go into the other one, diplexed with 
1430. (But, yes, they're skinny little things and not very tall, either.)

And Entercom would want its direct format competitor (to both of its big 
AMs) on its AM towers why exactly?

Since we're talking about what's essentially an emergency auxiliary 
antenna, I still think the best bet might be some sort of folded unipole 
strung on the tower behind the CBS Radio studios. It's an 
industrial/commercial area that's unlikely to generate much in the way 
of NIMBY action, and the entire facility would be under CBS control this 

As for the WBZ-TV tower...remember that CBS doesn't own it anymore. What 
would Richland charge for stringing a folded unipole all the way up that

I don't think the flooding problem at Hull is so serious as to render it 
unusable as an aux site. How often have the elevated tower bases gone 
under water in the 71 years the site's been in use?
