Human Factors; Procedure
While flying into BUR; was assigned Runway 33 due to high winds out of the north. Initially we were assigned the RNAV but we communicated we did not have the charts and were then given vectors. After being cleared by approach for the visual; I dialed in 2200 feet which was Traffic Pattern Altitude for the field. As I started the descent on the heading given for a base by ATC a 'caution obstacle' alert was announced. I immediately disconnected the autopilot to stop the descent; added power to climb; and turned the aircraft more towards the final leg away from last given heading since we were cleared for the visual. As I made the turn away from said obstacle; the first officer made an observation there was an antenna in close proximity. We continued to a stable final approach to landing and landed without further incident.
Air Carrier Captain reported receiving an obstacle alert during descent on a night visual approach to runway 33 at BUR.
