installations when spacing from transmit antennas is at least 1/10-wavelength or more.
When using radio systems and RF amplifiers an optional time sequencer such as the
Time Variable Sequencer Unit
should be used to ensure the correct timing while switching
from receive to transmit, and back to receive to protect the active receive antennas.
DXE-AAPS3-1P Active Antenna Phasing System
Package and Features

DXE-NCC-1 - Receive Antenna Variable Phasing Unit
Reduce overload or interference by nulling a strong signal or noise before it gets to your receiver
Better and more stable nulling than any other noise canceller or phasing unit on the market
Peak weak signals hidden under a strong signal on the same frequency
Null out local AM broadcast stations
Null out noise from power line arcing, lamp dimmers, motors and consumer electronics arriving
from a single direction
Best alternative to DX Engineering's Receive Four-Square antenna
Combine two antennas to create a directional pattern
The NCC-1 enables you to adjust the antenna array pattern as if you were moving the antennas
Special Features
Exceptional Dynamic Range, nearly 1000 times better than nearest competitor
Phasing is voltage controlled allowing precise resetting of phase
Phasing rotates more than 360 degrees with smooth control
Built-in two channel voltage controlled attenuator system
Low noise, high dynamic range amplifiers
Vastly superior dual channel complementary phasing system
Very low noise floor
Separate controls for reversing channel and phase
Works on all modes, 300 kHz to 30 MHz
Provides power for external active antennas
Input for mute on transmit
A sequencer such as the
should be used to ensure the correct transmit to receive switching
when operating with a high power amplifier.
