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 Heavy-Duty 4130 Chromoly Steel Masts
DX Engineering offers Heavy Duty 4130 Chromoly Steel Masts in both 11 foot and 22 foot lengths. DX Engineering Heavy-Duty 4130 Chromoly Steel Masts offer ham radio operators an opportunity to stack large antennas. These 2-inch and 3-inch outside diameter galvanized masts feature a 0.250-inch wall thickness and meet ASTM A-513 Type 5 ratings. These high-strength carbon steel masts are cold-drawn and electric-welded with a specified yield stress rating of over 100,000 psi! Tensile strength minimum is above 110,000 psi. Minimum Rockwell B hardness is 96. They are temperature stress-relieved to ensure consistent mechanical strength. Compared to standard galvanized plumbing pipe, the Heavy‑Duty 4130 chromoly steel mast offers substantially greater strength and durability. The galvanizing on these masts meets ASTM A123/A123M specifications. As with all hot dip galvanized products, surface irregularities are normal. Any cut ends are protected with a cold galvanizing coating. Important: Because these masts are galvanized, their overall outside diameter will be larger than the nominal size. The 2 inch mast may measure up to 2.070 in. OD, and the 3 inch mast may measure up to 3.130 in. OD. Are you planning on stacking a few mono-banders on the tower? Are you going to have multiple Yagis stacked high and deep on an H frame? Are you raising a BIG log-periodic? If you are going to loft big antennas with a lot of wind area, then you absolutely need a DXE Heavy-Duty 4130 Steel Mast atop your heavy-duty tower! DX Engineering Heavy-Duty 4130 Chromoly Steel Masts may be ordered and picked-up at the Summit Racing Equipment Retail Store, 1200 Southeast Ave, Tallmadge, OH 44278. Because of their length, these masts require truck freight shipping. Our system automatically calculates our low cost truck freight rates to any location within the continental United States. With no obligation to purchase, simply click ADD TO CART, enter your ZIP Code, and click CALCULATE to view your shipping cost. Due to size restrictions, air freight is not available. For information regarding a surface freight shipment of these masts to locations outside of the continental US, send an e-mail inquiry to dxengineering@dxenginering.com.

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. Make your SO2R or other multi-radio multi-antenna operations easy with a DX Engineering Dual Input Remote Antenna Switch.
