PRO-STACK Three Antenna Phasing Systems DX Engineering’s PRO-STACK phasing systems allow you to combine identical Yagi, Log Periodic Beam or quarter-wave vertical for enhanced performance. The systems promote broadband coverage of the 160-10M bands in a dozen in- and out- of-phase antenna configurations. This system provides impressive nulls (up to 40 dB!), so you can ward of unwanted signals and snag that rarest-of-rare QSO. The system consists of a relay unit and control console; each component is also available separately. PRO-STACK systems will easily handle the full legal limit and are powered by any 12 Vdc source. Nine-conductor control cable is required for operation. Choose your system based on the connector type you prefer: 7-16 DIN, SO-239, or type N. Use keywords “PRO-STACK” at DXEngineering.com for the details. DXE-PS-3B-P PRO-STACK Three Antenna Phasing System, SO-239 Connectors ......................................................... $1,105.98 DXE-PS-3BDIN-P PRO-STACK Three Antenna Phasing System, 7-16 DIN Connectors ....................................................... $1,101.98 DXE-PS-2B PRO-STACK Broadband Two Antenna Phasing System The PS-2B PRO-STACK combines two identical Yagi, log periodic or vertical antennas in a phased arrangement. It is a broadband system that operates from 160 through 10 meters with no need for coaxial delay lines. The PS-2B can be used in applications requiring these four basic antenna feed selections (impedance matching automatically changes when any antenna port is disconnected). • Both antenna ports in-phase (default) • Both antenna ports out-of-phase • Antenna port 1 only • Antenna port 2 only Additional Applications • Scalable Multi-Antenna Systems-The PS-2B easily adapts to larger arrays. For example, four stacked Yagis can be combined by creating two sets of two and using a third PS-2B to combine the first two sets. • Phased Verticals-The system can feed three vertical antennas in a four-pattern array. In this arrangement, the three antennas are individual quarter-wave resonant antennas. The center #2 passive element must be directly grounded at all times. Elements #1 and #3 are then fed in various phase relationships. Additional Features • 50 Ω system—switched by applying 12-15 volts DC to three control wires • Power handling up to 5 kW • High-impact RF-shielded cover • High RF-tolerant, silver-PTFE UHF connectors • Proven high-performance DX Engineering RF Relays • Safe 12-volt relay operation • MOV surge protection on control lines • RoHS-compliant DXE-PS-2B PRO-STACK Anetnna Switch ..............................................$599.99 DXE-PS-2B-P PRO-STACK Antenna Switch and Control Console ...........$795.98 The Control Console is also available separately. DXE-EC-PS2 PRO-STACK Control Console ..............................................$195.99 Note: Information on the appropriate separation between stacked Yagi antennas in versatile, high-performance array is discussed fully in the ARRL Antenna Book. Generally, stacked Yagi antennas are separated vertically by greater than 1/2-wavelength free space. DXE-PS-2B-P DXE-PS-3BDIN-P Antennas & Phasing Systems Skyhawk™ and Skylark Antennas. The legendary Skyhawk and Skylark antennas have been mainstays of international DXers and distinguished HF contesters for years. Both antennas have been brought under the DX Engineering manufacturing umbrella. That means these highly regarded antennas are built to DX Engineering’s unflinching quality standards. DX Engineering also carries all of the service parts you’ll need to keep these antennas operating ef iciently. Skyhawk™ Yagi Antenna With over 7 dB gain on the 20 and 15 meter bands, plus over 9 dB on the 10 meter band, the DX Engineering Skyhawk has become the choice of experienced HF DXers. A trap-free design ensures the best bandwidth possible. The use of aluminum and stainless steel hardware keeps the antenna’s overall weight down to around 75 pounds. The Skyhawk has a 23 foot boom. It is easy to build and tune, and comes with a 2,500 watt feedpoint choke. DXE-3X10 Skyhawk Yagi Antenna .....................................................$2,350.97 DXE-3X10 Skylark™ Dual-Band Yagi You get almost 8 dB gain on the 17 and 12 meter bands with the DX Engineering Skylark. The antenna also provides an SWR under 1.3 to 1 across each band, plus a front-to-back over 20 dB. It handles the legal limit plus! The Skylark’s simple design eliminates any moving parts, which contributes to all-weather reliability. Aluminum elements and stainless steel hardware also promote corrosion resistance. With a boom length of just 16 feet, the Skylark can handle winds up to 90 mph. A feedpoint choke is included. DXE-2X7 Skylark Dual-Band Yagi ...................................................$1,709.99 DXE-2X7 DXEngineering.com is loaded with detailed photos, specs, videos, and more!
