When the two captains of a falcon failed to note the 720 MSL crossing restriction at webac while conducting the RNAV (GPS) runway 8 approach to 3r7 they descended too quickly and triggered an egpws warning. The performed a map and diverted to their alternate airport.

Narrative:
While flying the RNAV (GPS) runway 8 at 3r7; we received a GPWS obstacle warning at approximately 600 ft. We executed a go-around and missed approach. Weather was right at minimums; so I was planning to get down to MDA ahead of vertical glidepath. Failed to notice the 720 ft crossing restriction at webac; so if we had continued down to 500 ft; we would only have had a 152 ft clearance near a tower located 3 miles from the runway. We shot another approach; but the weather prevented a landing. We diverted to our alternate. Autopilot was on; with vertical speed mode engaged when the event happened.to prevent this in the future I will plan a more careful review of the approach plate and will fly close to the generated vgp rather than using the 'dive and drive' technique.
