Radio tower question: WLLH?

What was the big old vertical radiator that used to stand on a hill on the 
west side of 495 between Lawrence and Lowell?  It was at Exit 39, I think 
(Route 133).  It was replaced sometime back in the '90s, if memory serves, 
but was there for years and years before that.  It was a very sizeable 
tower. Was it associated with WLLH, WCCM or what?

Also: Assuming that WLLH stands for "Lowell, Lawrence, Haverhill" (?), did 
the station ever actually have a physical presence in Haverhill?
