DX Engineering PRO-STACK Broadband Antenna Phasing Switches
DX Engineering PRO-STACK Broadband Antenna Phasing Switches are newly designed to combine two identical Yagi or log periodic beams, or three quarter-wave vertical antennas, into a phased array for enhanced operation. There is no need for coaxial delay lines with the DX Engineering PRO-STACK switches. Just connect your antennas to the phasing switch controller with equal-length 50 ohm lines. PRO-STACK switch units are available with high-quality PTFE-silver plated SO-239 (UHF female) connectors. These relay units are 1-of-3 source voltage controlled at 12-15VDC over a four conductor cable. A matching Control Console is available separately or is included in the PRO-STACK System. These phasing switches can be used for any applications that require the following four basic antenna feed selections: both antenna ports in-phase, both antenna ports out-of-phase, antenna port 1 only, and antenna port 2 only. The default is both output ports in-phase. Impedance matching automatically changes when any antenna port is disconnected. Generally, stacked Yagi antennas are separated vertically greater than 1/2-wavelength free space. Since the DX Engineering PRO-STACK Broadband 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 two, and then using a third DX Engineering control console to combine the first two sets. PRO-STACK switches can also be used to feed three quarter wave resonant vertical antennas for a high-gain 4-pattern array. In this arrangement, the center #2 passive element is directly grounded to a good ground radial system at all times, while the end 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. Features of the DX Engineering PRO-STACK Broadband Antenna Phasing Switches include these great features: * Power handling up to 5 kW * Broadband coverage on 160-10 meters * High-impact RF shielded weatherproof housing * High-RF tolerant, silver-PTFE SO-239 (UHF female) connectors * Proven DX Engineering RF relays for high performance * Safe 12 VDC relay operation, even on battery or solar power * MOV surge protection on control lines * External, removable control line connector * RoHS-compliant assembly

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.

So all of them need only be as long as the longest, to reach from the antennas to the relay unit.

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-800DXA 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 20 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-800DXA, 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-800DXA Medium Heavy-Duty Rotator System from DX Engineering.

DX Engineering Aluminum Tubing
DX Engineering High-Strength Aluminum Tubes are ideal for your antenna building projects. It is made available in sizes that fit into and over the next, with close tolerances specifically designed for strength when joined and overlapping only by a few to several inches, to build Yagi, Moxon or vertical antenna elements. NOTE: This tubing is NOT intended for each size to telescope completely into the full length of the next; it cannot be used for telescopic mast building. DX Engineering aluminum tubing is manufactured to very close tolerances. This provides the greatest amount of surface contact between nesting tubes for mechanical and electrical stability. Due to the close tolerance, any burrs, dirt, grit or other foreign material, as well as dents, dings and unseen bending or crushing suffered during shipment will cause binding that prevents this aluminum tubing from fully nesting. 6063-T832 seamless drawn aluminum tubing is available in 3, 6 and 12 ft. lengths. 6063-T832 tubing provides good resistance to general corrosion, including stress corrosion cracking, and an excellent surface appearance. Use a series of 3 ft. lengths to build an element that tapers more quickly for lower wind-resistance applications. Use a series of 6 ft. lengths to make an element that tapers more slowly for greater strength and bandwidth. The 12 ft. lengths are great for HF Yagi construction. Most sizes (except 12 ft.) are available slit on one end for use with DX Engineering stainless steel element clamps. If un-slit ends are required for your applications, merely insert the slit end into the next larger size in the stack and use your own attachment method. 6063-T832 tubing features a 0.058 in. wall thickness and is available in 1/8 in. increments from 3/8 in. to 2-1/8 in. O.D. 3003-H14 drawn aluminum tubing features a 0.035 inch wall thickness and a 1/4 inch outside diameter. Each piece is supplied with non slit ends and is available in both 3 foot and 6 foot lengths, making them ideal for your antenna building projects. If your setup requires maximum strength at very long assembly lengths, then choose DX Engineering 6061-T8 tubing. This heavy-duty version features a 0.120 in. wall thickness and is available in 1/4 in. increments from 1-1/2 in. to 3 in. O.D. Packaged shipments of 6 ft. tubing have oversize shipping fees, regardless of the number of 6 ft. pieces. Therefore, order more 6 ft. pieces to spread oversize fees over more tubing for a more cost effective shipment. Tubing that is 12 ft. long MUST be shipped by truck freight. If you need many pieces of the same size in a 12 ft. tube length, then buying DX Engineering High-Strength Aluminum Tubing Bundles (elsewhere in our catalog) maximizes the economy of scale for your shipping costs. NOTE: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Order DX Engineering High-Strength Aluminum Tubing here.

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.
