DX Engineering PS-3B PRO-STACK Three Antenna Phasing Units
DX Engineering PS-3B PRO-STACK Three Antenna Phasing Units offer the ultimate performance for combining three identical Yagi or Log Periodic directional antennas and may be used for vertical antennas in a phased array that cover any band, from 160 through 10 meters. Pro-Stack frequency independent broadband phasing devices operate optimally with three properly spaced mono-band antennas, but can be used with three identical stacked multi-band beam antennas, for pattern and null steering that wins contests and snags the rarest DX! Signals arrive at your antenna system from different azimuth directions and different elevation angles. Adding a stacking phasing system to a rotational array adds the ability to steer the pattern of the antenna array in two planes, azimuth and elevation, and to move the major lobe and nulls. The greatest advantage of Pro-Stack arrays is the ability to move harmful pattern nulls away from signal arrival angles. While gain makes a marginal improvement, moving a 20 to 40 dB null can be a phenomenal change, so the Pro-Stack can make the difference between a barely readable and a strong signal, providing the performance edge needed to work rare DX - and win contests. DXE-PS-3B Pro-Stack Phasing Units are 50 ohm relay systems that handle up to 5 kW. A separate user-supplied automated controller or the optional DX Engineering DXE-EC-PS3 Control Console for these 12-position rotary switch selections: - Three antenna ports in phase, default with no power to control console. - Antenna port 1 only - Antenna port 2 only - Antenna port 3 only - Port 2 out of phase, Port 3 in phase - Port 1 out of phase, Port 3 in phase - Port 1 out of phase, Port 2 in phase - Ports 2 and 3 in phase - Ports 1 and 3 in phase - Ports 1 and 2 in phase - Ports 1 and 2 in phase, Port 3 out of phase - Ports 1 and 3 in phase, Port 2 out of phase - Port 1 out of phase, Ports 2 and 3 in phase These PRO-STACK units may also be used for other applications requiring these feedline selections. To ensure lowest SWR, impedance matching automatically changes when any antenna is disabled. By switching between antennas at different heights above ground and/or changing the phase relationship between multiple antennas. The old standard system in stacks was to activate or disable specific antennas in the stack to change pattern. However, with the Pro-Stack system, gain remains higher when all antennas are driven and phase is changed, plus this system allows phase inversion as well as the ability to switch any single antenna out of the array. DXE-PS-3B Broadband Phasing Units provide the greatest flexibility for three identical antennas. This relay unit contains a broad-bandwidth high-power 2:1 impedance matching transformer. This eliminates common requirements of using mixtures of 75 ohm and 50 ohm phasing or delay cables for impedance matching. Feedlines to each antenna from the relay unit must be the same cable of the same length and match the antenna impedance. DXE-PS-3B Pro-Stack Broadband Three Antenna Phasing Units feature: - Power Handling up to 5 kW - Broad band coverage on 160-10 meters - RF Shielded Weatherproof Housing - unique protection - DXE-PS-3B has High-RF tolerant, silver - PTFE UHF connectors - DXE-PS-3BDIN has Amphenol Connex 7/16 DIN Panel Connectors - DXE-PS-3BN-P are made with high-quality silver-PTFE Type N female connectors - Proven high current DX Engineering RF Relays - Safe 12 volt dc relay operation - MOV surge protection on control lines - RoHS compliant assembly Get a DX Engineering PS-3B PRO-STACK Three Antenna Phasing System for your winning antenna array.

DX Engineering PRO-STACK Broadband Antenna Phasing Systems
DX Engineering PRO-STACK Broadband Antenna Phasing Systems are designed to combine two identical Yagi or log periodic beams, or three quarter-wave vertical antennas, into a phased array for enhanced directional pattern selections and dramatically improved HF operations. There is no need for special coaxial delay lines with the DX Engineering PRO-STACK systems. Just connect your antennas to the system relay unit with equal-length 50-ohm coaxial cable assemblies. The PRO-STACK switch relay units are available with high-quality PTFE-silver plated SO-239, UHF female connectors. The matching PRO-STACK Control Console operates the system with a 1-of-3 source voltage control format at 12-15V DC with a user supplied four conductor control cable to achieve four different antenna phasing selections. PRO-STACK Broadband Antenna Phasing Systems operate across the 160 to 10 meter range. They have two antenna ports that can be used for any application requiring the four basic selections: 1. BIP - Both antenna ports In-Phase 2. BOP - Both antenna ports Out-of-Phase 3. BOTTOM - Antenna port 1 only 4. TOP - Antenna port 2 only. The unpowered default is 1 - Both ports In-Phase. Impedance matching is automatic in the PRO-STACK even when any antenna port is disconnected. Generally, stacked Yagi antennas are separated vertically with greater than one half wavelength free space. Since the DX Engineering PRO-STACK Antenna Phasing Systems are broadband, they may be easily adapted to larger arrays. For example, four stacked Yagis may be combined by creating two sets of PRO-STACKS, with a third DX Engineering PRO-STACK to combine the first two. PRO-STACK systems may also be used to feed quarter-wave resonant vertical antennas for a high-gain, 4-pattern array. This arrangement requires three verticals, with the center #2 passive antenna element directly grounded to the system ground radial system at all times, while elements #1 and #3 are then fed in various phase relationships by the PRO-STACK. Details are in the complete PRO-STACK PS-2B Instruction Manual linked here in "Documentation" tab. The full- color printed manual is included with the system relay unit. PRO-STACK Broadband Antenna Phasing Systems are available as separate Relay Units for operators who have automated BCD switching devices, and as packaged systems with Relay Unit and matching manual Control Console.
