Narrative:
Upon departure from teb at approximately 2.5 mi our aircraft lost its DME signal from the teb VOR. Using a weak cross fix from patterson NDB; I determined that we were in excess of 4.5 mi from the VOR as specified by the teb 5 departure for a climb from 1500 ft to 2000 ft. At approximately 1800 ft in the climb; the DME readout came back on and showed 4.0 mi. I leveled at 2000 ft and advised ATC of our altitude.

Narrative: UPON DEP FROM TEB AT APPROX 2.5 MI OUR ACFT LOST ITS DME SIGNAL FROM THE TEB VOR. USING A WEAK CROSS FIX FROM PATTERSON NDB; I DETERMINED THAT WE WERE IN EXCESS OF 4.5 MI FROM THE VOR AS SPECIFIED BY THE TEB 5 DEP FOR A CLB FROM 1500 FT TO 2000 FT. AT APPROX 1800 FT IN THE CLB; THE DME READOUT CAME BACK ON AND SHOWED 4.0 MI. I LEVELED AT 2000 FT AND ADVISED ATC OF OUR ALT.
