Procedure; Airport
Never before have I been closer to crashing an airplane than today when I discovered yet another hazard at Teterboro Airport (TEB).  I was about 6 miles northwest of TEB when I was cleared for a visual approach to Runway 19.  I was number 1 for the field and I was told to keep my speed up because I had numerous jets behind me.  I maneuvered for a right base to the runway and contacted the Tower.  About 2 miles out; I started getting GPWS warnings about obstacles.  I looked outside and saw buildings well below my altitude so I wasn't concerned.  About 1.5 miles out I was shocked to see a 600+ foot tall radio antenna pass about 50 feet low and about 250 feet off my left wing.  Just after I passed the antenna; Teterboro Tower called to warn me about it.  Talk about a day late and a dollar short. By the grace of God; I missed the antenna.  I was shocked to see it.  Afterward; I reviewed the situation in an attempt to figure out what went wrong.  Why didn't I know the antenna would be there?  I was able to pick out the antenna on the ILS 19 approach plate.  But while the antenna was within a normal approach slope to the runway; on the approach plate it was mixed in with a bunch of obstacles half as tall.  Shame on me for not noticing the obstacle when I briefed the ILS 19 approach.  But it would have been helpful if there was some sort of point-out that that particular obstacle would impact a normal approach to the airport.  Also; shame on me for disregarding the GPWS advisories when I thought them to be irrelevant.  In the future; I will attempt to respond more appropriately to those advisories.  However; since the obstacle wasn't readily visible - even on a clear day - I'm not sure how I would have maneuvered instead. In my 3;000+ hours of flying; I have never seen such a blatant hazard to navigation.  I don't understand how that antenna has not yet caused a tragedy.
CE340 Pilot reports ignoring an EGPWS warning during a right base visual approach to Runway 19 at TEB; caused by a 694 foot radio tower a half mile right of final and 1.6 miles from the runway end. Even though daylight VMC prevailed the tower was not detected visually until it passed by the left wingtip 50 feet below. A late advisory was issued by the Tower.
