Narrative:
The procedure for removal and installation of the broadband antenna requires two technicians work on top of the fuselage. The antenna alone weighs 80 lbs. The amm (aircraft maintenance manual) calls out to install a fixture handling assembly to the antenna. This fixture has provisions on it for use with a hoist. There is no overhead hoist at the hangar. Technicians have to move the 80 lb antenna by hand. There is nothing to attach the technician's safety harness to except to the lift basket. It is also very possible that in the future someone could accidentally lose their grip of the heavy antenna and drop it. That would in itself be a threat to the personnel below and the aircraft. This job should not be performed at the hangar because there are no overhead hoist. This job should instead be performed at the [maintenance hangar that] has two overhead hoist and is an appropriate place to conduct the removal and installation of the 80 lb broadband antenna.
