Features

Phase adjustable through at least 360 degrees in the primary design area
(500 kHz to 15 MHz)

Exceptional dynamic range - able to handle strong signals without overloading

Low noise floor

Provisions for optional internal high pass and band pass filters

DC controls with smooth repeatable action. Expandable for remote or external control

Provides power and transmit muting for external active antennas

Antenna and Receive Outputs use RCA phono and Type F connectors to help prevent
accidental connection to live transmit feedlines
The
NCC-1 has four main advantages over typical phased antenna systems:

The array can be electrically "steered" or directed using physically stationary antennas

The user can adjust direction and wave angle of either a null or peak

The response can change from a signal null to a perfect signal peak with a flip of a single
switch

Front panel adjustments compensate for less-than-ideal installations, making a directional
array possible in most situations
NOTE: The NCC-1 is a
Receive-Only
phasing system. It is designed to go between
the receiver input port of a radio or transceiver and two receiving antennas.

Do NOT transmit through the NCC-1

If transmitted energy is ever allowed to reach the antenna or receive output ports of the
NCC-1 , serious damage may result in a burned out unit.
If this occurs either by intermittent misuse, neglect, or accident, any warranty would be
voided and your NCC-1 may not be repairable.
Operation of the NCC-1 with Active Receive Antennas in close proximity to transmit antennas (1/10-
wavelength minimum) and high power operation with a linear amplifier requires additional optional
equipment. See Appendix A for details.
The
NCC-1 is not a Digital Signal Processor (DSP) unit and it is not a Noise Blanker. The NCC-1 is a
receive signal RF phasing controller with exceptionally low noise, high dynamic range, level control and
phasing range.
