The "Alpine" is not a building. It is called the Alpine Tower and is on a "mountain" in NJ. As a crow flys I believe it is about 2 miles from the former WTC. There are no digital broadcasts now...only analog.
It has been said that by the end of the year digital boradcasts will resume from this temporary site.
For some particulars on the history of this site, and Mark Schubin's compelling account of the terrorist attack's affect on broadcasting and, more importantly, "broadcasters," (people) read Mark Schubin's Monday Memo at www.digitaltelevision.com . There's a place to click on Mark's site just down the left side of the homepage.
The Apline tower is near the NJ - NY border atop the Palisades. It is visible from both the George Washington Bridge and Tappan Zee Bridge. That area is not a mountain per se, but more of a high plateau.
Speaking of NY antennas.... Check out the latest National Geographic magazine. They have two pictures of the antenna on the top of the Empire State Building. The pictures are of the person changing a light bulb on the top of the tower, it gives a unique and dramatic perspective.
