I guess this is why they say that It should gradually become more widespread. B8ZS is the preferred long-term method of providing Clear Channel. > B8ZS is preferable.

Of course B8ZS will cost more, because it requires special equipment to handle it. There is no particular reason why B8ZS can not be used in an SF format T1. If they only support B8ZS on ESF, it is due to limitations particular to the equipment they are using, or due to their own (marketing?) restrictions. JB
