This will *not* work if the antenna is placed *inside* the datacenter. The trick is to order a spot on the roof of the datacenter, have the facility staff place the antenna there, and run a cable to the NTP server in your rack. It'll depend on the facility what the MRC / NRC is for this service will be. Kind regards, Job
