The single NT configuration is composed of a single X-Pol RT and a single NT. The dual NT configuration
is composed of a single X-Pol RT and two NTs linked to the X-Pol RT via a splitter module. The single
NT configuration pre-wired for and additional NT is identical to the Dual NT configuration, except that the
second NT and associated cable is replaced by a 75 ohm termination load. This configuration is
recommended wherever a second NT may be required in the future, as it allows the installation of the
additional NT without removing the first NT from service.
