our solution
The 4SQ System
One complete solution built for performance.
System overview
Four parts. One powerful system.
Engineered to work together for maximum performance and ease of use.
1
Antenna phasing unit
The Antenna Phasing Unit controls the entire antenna system. It creates the correct phase and amplitude for each antenna element, resulting in the desired antenna radiation pattern.
2
Transimpedance Preamp
The Transimpedance Preamplifier transforms the high impedance of the short vertical antenna elements into a balanced 100 Ω system impedance.
3
Indoor unit
The 4SQ Indoor Unit transforms the balanced 100 Ω system impedance into a standard 50 Ω output for your receiver. It also distributes DC power and control signals between your radio station and the Antenna Phasing Unit located up to 300 meters away.
4
Azimuth switching console
The Azimuth Switching Console is the control center of the entire system. It manages antenna direction switching, enables remote operation, and allows you to steer the receive array from your PC or tablet.
