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. Features of the DX Engineering PRO-STACK Broadband Antenna Phasing Systems include: * Power handling up to 5 kW * Broadband coverage on 160-10 meters * High impact shielded weatherproof housing * High-RF tolerant, silver-PTFE SO-239 (UHF female) connectors * Proven DX Engineering RF relays for high performance * Safe 12V relay operation * DC-powered control console allows battery or solar emergency operation * MOV surge protection on control lines * External, removable control line connector * RoHS-compliant assembly Dominate the airwaves with DX Engineering PRO-STACK Broadband Antenna Phasing Systems. * Important Note regarding DX Engineering Protection Plans and Kit Combo Contents NOTE: Protection plans cannot be purchased for combination packages or on applicable devices after shipment.

Yaesu G-5500DC Azimuth-Elevation Rotator Systems
Yaesu G-5500DC Azimuth-Elevation Rotator Systems are specially designed to accommodate horizontal cross-booms to mount pairs of VHF and UHF directional antennas for space communications. Providing simultaneous control of 450 degrees of azimuth rotation and 180 degrees of elevation rotation, they are perfect for EME (moon bounce) and satellite communications installations. The G-5500DC dual controller lets you adjust and keep track of both aspects of the antenna system's positioning. The 120 VAC controller includes an interface jack for computer control, supported by the optional GS-232A Computer Controller, as well as many aftermarket control programs and interfaces. These azimuth and elevation rotators are actually two separate motor units, now DC controlled. They may be mounted together on a mast with the included mast bracket, or independently with the azimuth rotator inside a tower and the elevation rotator mounted on the mast above the top of the tower. They handle a total of about 10 sq. ft. of antenna wind load and rotate each way in about one minute. The Yaesu G-5500 AZ-EL clamshell rotator design utilizes 98 heavy 7/16-inch dual-stacked circumferential ball bearings to distribute load over the full diameter of the housing. This design minimizes stress and wear, and practically eliminates the possibility of destructive water entry: there is no shaft hole in the top of the housing. Yaesu's factory-lubricated rotator units are housed in Melamine resin-coated die-cast aluminum intended to provide maintenance-free operation under all climatic conditions. IMPORTANT NOTE: Beginning in 2019 the new Yaesu G-5550DC azimuth and elevation motors operate with two independent 22 V DC control lines, each a five-wire system, using the same connectors at the end of the control cable as the previous models. Both of the new DC motors, azimuth, and elevation, are marked "G-5550DC" at the connector. Be sure to mark your connectors AZ or EL. The rear panel of the controller is titled "G-5500DC" on the serial number label. WARNING: The legacy Yaesu G-5500 Rotator motors and controller used a 26 VAC control voltage, six-wire system. Therefore, old AC controllers are NOT compatible with new DC rotator motors, and new DC controllers are not compatible with old AC rotator motors. All control cable assemblies for all modern Yaesu rotator systems use the same connectors with "1 to 1 pin-out" connector wiring. Therefore, older cable assemblies are compatible with the new Yaesu G-5500DC components, which only use pins 1, 2, 3, 4 and 5 in each connector. For control cable runs less than 125 ft. use five-conductor, 20 gauge control cable (5 x 20 AWG). If the rotator cable needs to be longer than 125 ft. then use five-conductor 18 gauge cable (5 x 18 AWG). The input voltage for the G-5500DC controller is labeled "117 VAC" to indicate house current range of 110 to 120 Vac. When you are launching your EME or satellite communications adventure, an azimuth/elevation combination rotator is a vital tool for your antenna system. As durable as they are attractive, Yaesu G-5500DC Azimuth-Elevation Rotator Systems are available from DX Engineering.

Yaesu G-1000DXA Heavy-Duty Rotator Systems
Yaesu G-1000DXA Heavy-Duty Rotator Systems are azimuth positioners designed to rotate large tower-mounted amateur and professional antenna arrays under remote control from the station's operating position. These systems feature attractive compass-dial position indication controllers, with a connector port for optional computer interface for automated directional antenna positioning control. Yaesu's G-1000DXA rotator design utilizes 98 heavy 3/8 in. dual-stacked circumferential ball bearings to distribute load over the full diameter of the housing. This design minimizes stress and wear and practically eliminates the possibility of destructive water entry: There is no shaft hole in the top of the housing. Instead of the usual AC motor drive used in older rotator designs, the G-1000DXA use a variable-voltage DC motor, removing the need for a large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. A mast alignment gauge on the rotator housing simplifies accurate mechanical alignment during installation. Tower mounted, this model handles over 23 sq. ft. of antenna wind load and over 400 lbs. of vertical mast load. Installation is required for included plug connectors on to the installer supplied 6-conductor control cable; 20 AWG for lengths less than 125 ft. and 18 AWG over 125 ft. Console power is 117 volts AC for units sold in the USA. The handsome desktop controller provides 360 degrees radial indication of actual antenna azimuth bearing. You can select rotation time over 360 degrees from 40 to 100 seconds on the G-1000DXA, and preset a desired heading for the rotator, to which it then turns automatically. The operator may select the stop heading, the compass bearing through which the rotator cannot be turned, which is most convenient for their station location and operation, allowing full rotation through north, south or both, if desired. In any case, 90 degrees overlapping rotation allows rotation through the selected stop heading for 450 degrees of total rotation. These rotators are intended for mounting to an accessory shelf inside a support tower (not supplied), at least 1-meter (40 in.) below the top of the tower. Yaesu rotators have a fine reputation within the Amateur Radio community. When installing a new tower, or replacing an old rotator, consider purchasing a Yaesu G-1000DXA Heavy-Duty Rotator System from DX Engineering.

The maximum transmit power is 5 kW with SWR less than 1.1:1 in the range 50-50.45 MHz with average gain of 12.9 dBi. This antenna was specially designed for G3WOS, who was looking for a perfect antenna for 6m for his free standing mast. The relatively long boom provides good gain with excellent front/rear ratio, so this antenna is great for EME and "weak signal" DX. This antenna has very highly suppressed lobes in both azimuth and elevation plots and therefore is ideal for very noisy city locations. If you want to beat the noise in a mid-sized 6m antenna, this is the one for you! The G0KSC LFA Yagi is a major step forward in the development of the Yagi Antenna; it provides a low-noise front-end for your radio so you hear more weak signals. This 7 element 50 MHz LFA2 is another exciting slant on the LFA design with both the last third of both the reflector and first director elements being bent towards the driver loop in order to enhance performance. Incredible levels of F/B have been achieved providing the ultimate in rear-end suppression. This antenna is made with tapered elements 16mm center and 13mm outer sections. The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which accommodate 2 inch (50mm) masts. Boom is 2 inch (50mm) aluminum in the center, tapering to 40mm with a 45mm section, all with 2mm booms. A boom guy system is provided with this antenna. Marine grade Stainless Steel Fittings Original Stauff Insulation clamps Mill finished boom and elements for highest levels of accuracy Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the components of our antennas have least effect on performance and pattern degradation.
