Unlike conventional IF noise blankers, the NCC-1 is designed to reduce noise or interference before it gets to the receiver. The NCC-1 can be effective on all types of noise, including interference (QRM) from unwanted signals. The NCC-1 allows the user to continuously adjust both phase and amplitude when combining two antenna inputs. The signal output to the receiver is the addition or subtraction of signals from two separate antennas. Unwanted noise can be removed or unwanted signals can be cancelled. Desired signals can be peaked or enhanced.

The NCC-1 generally works best when both antennas have similar patterns, polarization, and Signal-to-Noise ratios. For the most effective nulling of noise, both antennas must hear the same unwanted noise and should have similar polarization. The wanted and unwanted (QRM and QRN) signals must be arriving from different directions.
 
Low noise active receive antennas such as the DXE-ARAV3-1P are extremely effective when used with the DXE-NCC-1.  For an economical package of the DXE-NCC-1 and two DXE-ARAV3-1P antennas, see package number DXE-AAPS3-1P.

Noise Nulling Receive Antenna Controller
