WNBC-TV's CHOPPER 4 was sent to take a look at an icing condition at the top of World Trade Center's TV mast. Pictures are from winter 2000, and the cockpit chatter provides the audio for this footage. (PARENTAL ADVISORY:brief language ("Holy s***") @ 1:53) At WTC, WNBC-TV (channel 4) and WNYW-TV (channel 5) shared the top position on the mast, with both stations diplexed into a 2-bay batwing antenna, the RCA TF-2BM(S) 'superturnstile'. On this visit, the chopper found a good deal of ice on the north face of the antenna. Also included are shots of the 2-way radio antenna farm and other equipment on the deck of #1 World Trade Center. Lots of ice, which has fallen off the mast can be seen at the base of the mast. At the end, there's a brief look at the observation deck of WTC tower 2.
