Assuming the date is accurate (which might be the first mistake) The New York Times shows only two ships coming in >from Antwerp on that date. One was called the Rotterdam and the other the American. Arriving the following day on November 26th was the Vaderland >from Anwterp and nothing is reported arriving >from Antwerp on November 24th.
Armed with this information I went to Ancestry and did some searching both on the ship's name and on the date. I hate to say it but I do not think the lists for the Rotterdam or the American are loaded. I see the Vaderland's list on November 27th but there are basically no names on the 25th and only a few ships on the 26th and not the ones you need.
Maybe someone can come up with a different answer using wild card searches but I would suggest looking for see if the lists for the Rotterdam or the American exist at all. The National Archives should be able to tell you if those lists exist. Also I believe lists exist >from Holland for the Holland-American Line ships. I am not sure if they cover the embarkation in Antwerp but it might be an alternative if the New York arrival lists are missing.
According to my great-uncle's Petition for Naturalization (No. 156627), Jacob Salb came into the United States through New York City on November 25, 1906...
