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.

Feedlines to each antenna from the relay unit must be the same cable of the same length and match the antenna impedance. So all of them need only be as long as the longest, to reach from the antennas to the relay unit. While it is best to have feedlines of equal electrical lengths, there is no need to closely phase-match cables; cutting the antenna feedlines made from the same coax to equal physical lengths is sufficient.

DX Engineering Dual Input Remote Antenna Switches
DX Engineering Dual Input Remote Antenna Switches are two-radio 8-antenna switches (2x8) designed to switch coaxial lines in medium to high power RF antenna systems. With excellent performance on HF and 6 meters, they are typically used in single operator two-radio (SO2R) or multi-two contesting stations. They offer high levels of port-to-port isolation and reliability, the same as the famous DX Engineering RR8 series single input 8-port remote antenna switches. Manual dual-control operation of the DXE-RR2X8B is possible with two separate 1-of-8 control consoles that send +13.8VDC to the selected port, such as the DXE-EC-8. In this instance, the main transceiver has precedence over the secondary when attempting to use the same antenna port, so manual switching care must be exercised. An alternative first come, first served switching approach is available with the optional DXE-MX2X8 Interface Unit. It accepts BCD signals from two DXE-CC-8A Deluxe Control Consoles, and it locks out the selected port from the other radio, rather than main port precedence. DX Engineering RR2X8B Dual Input Switches may be interfaced with a customer-supplied logical switching unit. A third-party antenna controller with dual 1-of-8 switching may be used directly with the DXE-RR2X8B Switch or with BCD to the DXE-MX2X8 Interface Unit. If the DXE-MM2X8 Interface Unit is not used, the third party unit must provide protection against hot switching and prevent the main or secondary radio ports from attempting to select the same antenna port at any time. DX Engineering Dual Input Remote Antenna Switches feature a custom-made stainless steel chassis and a special RF shielded high impact thermoplastic cover. They have a custom conductive gasket to complete the seal between the cover and stainless steel housing base. Disassembly is not required for control wiring access. DX Engineering RR2X8B switches use removable screw terminals for the control cable plugs. These removable plugs greatly simplify installation by eliminating the need for soldering or opening the enclosure. The internal, covered relays are moisture-resistant, providing many years of exceptional performance. The circuitry of the DXE-RR2X8B switches allows the simultaneous selection of multiple antenna port with the required control signals. They can be used in complex antenna systems including stacked and phased arrays. Also, conventional one-of-eight antenna switching for two separate stations is possible using separate 1-of-8 switching arrangements. For example, the main radio Input "M" may select and be connected to any of the 8 ports while the secondary Radio Input "S" can simultaneously select any of the ports that the main isn't using. The main controller always has precedence over any selection made by the secondary controller, unless the DXE-MX2X8 is employed. Features of DX Engineering Dual Input Remote Antenna Switches include: * Rugged, attractive, fully shielded weatherproof housing * DX Engineering stainless steel V-clamp included for easy mounting to tower legs or masts from 1-2 in. diameter * Multi-conductor external cable plugs for easy removal, connection and maintenance * Excellent port-to-port Isolation; greater than 70 dB at 30 MHz, worst case; greater than 60 dB up to 60 MHz * High RF tolerant UHF connectors * Enclosed 16 ampere RF relays * Safe 12V DC relay operation * 16 MOVs for surge protection on control lines * 16 RF bypass capacitors Note: Whenever the DX Engineering "Documentation" is available, please look at the associated files for additional product information.

DX Engineering Maxi-Core® 20 Baluns and Feedline Chokes
The present-day DX Engineering was launched in the year 2000. To celebrate our 20th Anniversary in the year 2020 we have developed a new line of Baluns and Feedline Chokes. Introducing DX Engineering "Maxi-Core® 20" Baluns and Feedline Chokes. They reduce or eliminate currents on the outside of your feedline allowing you to hear and to be heard much better. They keep more RFI/BCI out of your antenna and receiver and transfer more of your transmitted signal to the antenna for higher efficiency, the best antenna pattern and maximum performance. Signaling a new era of RF performance across the 1.8 to 54 MHz frequency range, DX Engineering Maxi-Core® 20 Baluns and Feedline Chokes handle full-legal-power-plus and provide higher common mode impedance (CMI) across a greater frequency range than competing models and even previous DX Engineering and Comtek models. Years of R&D coupled with major advancements in test equipment and techniques combined with custom ferrite materials have allowed our engineering team to design the DX Engineering Maxi-Core® 20 Baluns and Feedline Chokes. Maxi-Core® 20 Baluns and Chokes have high CMI across the AM Broadcast band and the HF/6M spectrum, which is essential to provide sufficient suppression of unwanted transmitted and received RFI/BCI current on the feedline shield exterior. Hear and be heard with DXE Maxi-Core® 20 Baluns and Feedline Chokes. Choose superior performance from these models: * DXE-MC20-1-1 Maxi-Core® 20 - 1:1 Current Choke Balun - For all HF-6m balanced antennas with a 50 ohm feedpoint, including resonant dipoles, loops, Yagis, beams, etc. * DXE-MC20-FC Maxi-Core® 20 - 1:1 Feedline Choke – This high CMI line isolator is perfect for use in line on 50 ohm coaxial feedlines, at the antenna, tower or shack end of the feedline. * DXE-MC20-1-1T Maxi-Core® 20 - 1:1 Current Choke Balun – This 1:1 "T" model is for force feeding antennas with a tuner. Use it at the end of ladder line of any impedance or mounted on a coax fed non-resonant antenna. This model tolerates operation at high SWR on non-resonant multi-band antennas. * DXE-MC20-C4-1 Maxi-Core® 20 - 4:1 Current Choke Balun is for use on antennas with a 200 ohm feedpoint and at the end of any impedance ladder line, especially on antenna systems with higher impedance. This model tolerates operation at high SWR on non-resonant multi-band antennas. * DXE-MC20-V4-1 Maxi-Core® 20 - 4:1 Voltage Balun is a 200 ohm to 50 ohm transformer for use on random long-wire and OCF antenna applications. This true voltage balun is intentionally designed with low CMI for antennas that need a transformer without RF choking for easier antenna tuner operation and it tolerates elevated SWR. Maxi-Core® 20 Baluns and Feedline Chokes are built into a convenient weather resistant NEMA enclosure that is mounted easily with optional brackets. They feature 1/4-20 stainless steel hardware and a high quality silver-plated PTFE dielectric SO-239 (UHF female) input connector. The SO-239 connector limits power handling to 5 kW at low SWR and reduced power at elevated SWR. These baluns and the feedline choke exhibit very low insertion loss and inherently low SWR. Optional mounting brackets are available for use on wire antennas or for verticals, Yagi and beam antennas. See the Suggested Parts tab after clicking "More Detail" on the model of interest. Combination packages that include balun or choke and mounting bracket are also available.
