Receive Four-Square Complete Array Packages
DX Engineering Receive Four-Square Complete Array Packages are advanced four-square receiving systems that use four symmetrically spaced elements to provide switching for a 4-direction receiving antenna system.
These unique systems use time delay phasing, rather than the single band phase shifting used in traditional four-squares. When used with active receive elements, this time delay phasing scheme provides the correct phase relationship across a wide frequency range, producing useful front-to-rear ratio (F/R) response over several bands.
These systems use directionally optimized time delays to produce wider and deeper rear nulls. Wide null areas and a narrow main lobe greatly reduce noise and undesirable signals. DX Engineering Receive Four-Square Complete Array Packages are more reliable than a conventional transmitting four-square system in receiving applications. Transmitting four-squares use large, exposed contact relays which can become contaminated or corroded. The RFS uses sealed relays with contacts optimized for receiving applications.
Features include:
* W8JI unique patented design
* Stainless steel chassis and hi-impact poly-resin drip edge cover for enhanced weather resistance
* Reduced susceptibility to high angle signals compared to EWE, Flag, Pennant, and K9AY
* Operates from 100 kHz to 30 MHz
* Excellent directivity in small space for better signal-to-noise ratio
* Switching of four 90 degree spaced directions
* Directivity over a very wide frequency range using DX Engineering Active Receive Antennas
* Requires less space than a Beverage antenna; active elements need only a minimal ground system
* Easier to deploy and maintain than a 4-direction Beverage antenna system
* Using active elements, system allows close proximity to transmit antennas using transmit/receive sequencer
* Enhanced relay contact reliability
* Low current, DC-powered control console allows system operation without AC power mains
Kits include:
* One DXE-ARAV3-4P package of four active receive vertical antennas with internal antenna disconnect relays
* One DXE-RFS-3 receiving four-square antenna switch
* One DXE-EC-4 four-position control console
* One DXE-TVSU-1A time variable sequence unit
* One DXE-6UF-1000 1,000 ft. rolls of 75 ohm self-healing coaxial cable
* Twenty-five DXE-SNS6-25 Snap-N-Seal connectors
* One DXE-SNS-CT1 Snap-N-Seal crimp tool
* One DXE-CPT-659 Coax Cable Stripping Tool with one replacement blade
