English: Atop is an ERI master antenna. The story of its installation is www.eriinc.com/news/pressroom/silliman_on_top.pdf. Stations radiating from there include WQXR/105.9, WNYC-FM/93.9, WLTW/106.7, WSKQ/97/9, WXNY/96.3, WWFS/102.7, WRKS/98.7, WBAI/99.5, WBLS/107.5, WWPR/105.1, WHTZ/100.3, WXRK/92.3, WAXQ/104.3 and WKTU/103.5. All are 6kw horizontal and vertical except for WBAI (4.3), WBLS (4.2), WQXR (.61) and WRXP (6.2). It appears from here that WRXP uses the gold one-bay while the rest use the white two-bay above. Next down is a WPLJ/95.5 auxiliary antenna (6.6kw) and then three stations sharing a two-bay panel antenna: WQHT/97.1, WPLJ/95.5 and WCBS-FM/101.1. All three are 6.7kw. The old Alford can be seen below. At the level between the two FM systems is the new master antenna for New York's three TV stations still using the VHF band: WABC-DT on Channel 7, WPIX-DT on Channel 11 and WNET-DT on Channel 13. Unlike most TV stations after the digital transition of 2009, these stations still broadcast on their original analog channels. For old times' sake, here is how the antennas on the ESB looked in 1967 (I remember these well). And here is NECRAT's page with a rundown of all the FM stations, matched to antennas. Not sure who's right about what here. Most of the stations are licensed to the same 50kw at 100 meters, and can easily switch between any of the antennas up there to achieve equivalent coverage within their licensed limit.
