What is the black thing at the beginning of intake? Is that the refueling probe? I always thought it was on the nose of the Phantom?
It's an antenna for the ALQ-126 active-jammer ECM system. The system replaced the ALQ-100 in the mid-'70s, and was an add-on (did not come from the factory with it).
The mod to the intake area consisted of a waveguide cover and the antenna (the black thingy) at the forward end of it. The F-4N's waveguide cover was about twice as long as the F-4J/F-4S cover, and makes one way to tell an N from an J/S (in addition to the IR dome under the nose of the B/N). [The first couple of squadrons that received N's did not have the ALQ-126, but were soon retrofitted.]
The Brits didn't use the ALQ-126, but their aircraft retained the antennas because it was too difficult to remove them.
The refueling probe was retracted behind a door that was more or less under the RIO's canopy. When extended, it was actually behind the pilot's head... the RIO would talk the pilot into the basket, while the pilot looked forward and flew formation on the tanker. You could tell when a pilot was peaking because the aircraft would go into PIO as the tip neared the basket.
