DX Engineering A/B Station Selectors
The DX Engineering A/B Station Selector Interlocked Coaxial Relay was designed for two-station multi-operator or SO2R contesting from 160 through 6 meters. Two radio inputs and one output for an amplifier, antenna or another relay, allow the AB Selector to function as two interlocked SPST normally open contact coaxial relays when controlled by a user provided SPDT switch or antenna selection automation. This device is a critical component that enables a single radio to access the shared output port while simultaneously isolating the other radio from that port. With over 80dB of isolation between the selected and unselected ports, there is no danger to the opposite receiver from high energy overload or burnout. In place of a manual switch, the AB Selector can be controlled from a distance, or remotely with automation, to select between two antennas or two remote antenna switches for one station feedline. It can also be used to remotely toggle a transceiver, amplifier or station output to either an antenna switch for normal operations or a dummy load for testing and tuning, instead of using a port on a remote antenna switch for the dummy load. Two A/B Station Selectors may be configured as a DPDT reversing switch, as shown in Figure 2 of the user manual, useful for switching two transceivers to two different towers, two antenna switches or two amplifiers that are tuned to different bands or segments, for Single Operator Two Radio (SO2R) stations. Several AB Selectors can be configured for a Multi-2 or Multi-Multi contest station in combination with third-party multi-port antenna switches and band decoders to create an automated band-specific antenna selector system. Contact DX Engineering for more information. The DX Engineering AB Station Selector is a drop-in replacement for the legacy TopTen Devices A/B Station Selector. This relay device features excellent port-to-port isolation, low SWR and low insertion loss, and is rated for full legal SSB and CW power on the 160 through 6 meter bands. This relay features three UHF female/SO-239 connectors, Radio-A, Radio-B and Common and a removable control connector with compression screw terminals. DC voltage input is +12 to 14VDC @ 110mA with sink-to-ground connections for A or B port selection. Neither A or B port is selected when neither A or B control terminal is grounded. The DX Engineering A/B Station Selector may be used for two different switching systems: one common input to two outputs or two inputs to a single common output. Figure 1 in the user manual shows how to connect a user provided SPST switch and power supply. For example, two radios or two amplifiers connected to A and B, can be switched to connect one antenna or antenna switch on the COMMON. Conversely, a single radio or amplifier connected to the COMMON port can be remotely switched between two antennas connected to A and B, or between two amplifiers feeding separate antennas. Alternatively, a station may use the switch to select between an antenna and a dummy load.

4O3A AB Switch Relay
The 4O3A AB Switch Relay is a high isolation A/B switch, needed for some applications such as extension of an antenna matrix. The most common use case is routing the antenna between two existing high isolation antenna switches, so the isolation of this A/B Relay isn't quite as high as the RS3000 or 1A2R. Additional isolation is realized by grounding of the unused port. AB switch is powered by 13-15V through a dedicated power connector. It has an LED to indicate "out B" status. When powered off the input is routed to out A. AB Switch Relay Specifications: Port-to-port isolation at 30MHz: 56db to 70 dB (On/Off status) RF Power Handling (max.): 4000W Connectors: 3 x SO-239 (O3A-4O-AB-PL) Power: 12V DC @ 120mA Power Indication: LED diode Dimensions, WHD: 3.35 x 5.31 x 2.76 in.

This combination system provides complete antenna selection automation when interfaced with the Acom 2000A Automatic HF Linear Amplifier, or it may be used as a manually or PC controlled antenna switching system. The included 2000SW Remote Antenna Switch is a rugged, high-quality weatherproof outdoor relay unit with 10 antenna ports and 1 common port, all PTFE UHF female (SO-239) connectors useable up to 60 MHz. At low SWR this switch handles up to 5,000 W at 30 MHz and 3,600 watts at 50 MHz. Hot-switching protection is provided and unused antenna inputs are automatically grounded for surge suppression. Relay water intrusion protection is at the IP53 level. These remote switches will tolerate a very wide temperature range and operate on a control voltage range of 24 to 31 VDC, as supplied by the 2000S Automatic Antenna Selector. The included 2000S Automatic Antenna Selector, as shipped in the ASW-120 package by DX Engineering, has a power cord terminated with a NEMA 5-15P plug for 120 AC. No additional power supply is required. The system uses a 4 bit BCD selector signal and incorporates a feedback signal to the controller. Connection of the 2000S Selector to the 2000SW Switch requires a minimum of a 7-conductor shielded control cable of AWG-24 (CAT5e) which is sufficient to about 165 feet. A longer control cable will require a larger wire gauge. Connectors included require soldering. Also included are a 3-meter length of 7-conductor control cable and 1 interface cable for connecting the controller to the ACOM 2000 amplifier. Here are the Specifications of the ACOM ASW-120 Remote Antenna Switch and Selector Sets: * Operating Frequency: 0 to 60 MHz. * 10x UHF female (SO-239) PTFE connectors * Power Handling vs. SWR: 0 to 30 MHz: 5000W at 1:1; up to 2500W at 2:1; up to 1600W at 3:1 * Power Handling vs. SWR: up to 60 MHz: 3600W at 1:1; up to 1800W at 2:1; up to 1200W at 3:1 * Mismatch VSWR: for 0 to 1.8 MHz better than 1.02:1; 1.8 to 30 MHz better than 1.08:1; 30 to 60 MHz better than 1.20:1 * Crosstalk isolation: for 0 to 1.8 MHz-better than -100dB; 1.8 to 30 MHz -better than -70dB; 30 to 60 MHz better than -66dB * Relay Changeover Time: Less than 150 milliseconds including any relay chatter * Operating temperature range: minus 30 to plus 60 degrees C * Water Intrusion: IP53 * Power Supply: 120 VAC, NEMA 5-15P three-prong power plug (USA) * Total shipping weight 6kg (products 4kg) NOTE: This Acom ASW-120 Remote Antenna Switch and Selector Set is available from DX Engineering ONLY as a 120 VAC system.

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.

4O3A A50 Antenna/Load Switches
4O3A A50 Antenna/Load Switches serve as 50-ohm loads for open ports on the HFC4500 combiner or other multiplexer, preventing tuning degradation. Applying 12V power connects the input to the combiner's output, linking it to the corresponding combiner or filter. A typical setup switches a filter or a combiner to a monoband antenna. When the A50 is not powered, the switch defaults to a 50-ohm termination for the input and the antenna output is open. NOTE: The A50 is NOT an A/B switch. The manufacturer's label of "A/B Switch" is a product grouping, NOT an indication of the function of this product. The LOAD resistor is internal, so one of three connectors is unnecessary, which leaves an open hole in the chassis, a "normal feature" of the A50.

SSB Electronic AS-3000A Mast Mount Antenna System Switch
SSB Electronic AS-3000A Mast Mount Antenna System Switch is an integral part of a low-loss preamplifier and power amplifier control for two-way VHF, UHF and SHF stations. Covering the entire range from DC to 3 GHz, two high quality SPDT coaxial relays, housed in their weather- and UV-resistant enclosure, provide excellent power handling and port isolation with minimal insertion loss. The solid aluminum chassis base incorporates a mounting bracket for a 1.5 to 2.4 in. mast clamp, with six downward facing Type-N female connectors for the antenna, a mast mounted preamp, a power amplifier and the station. A single Type-F connector provides DC out for the preamplifier and a 4-pin DIN with mating connector is used for direct DC control of the relays, typically with a sequencer. User supplied shielded control and power cables are recommended to prevent RF induced false keying. The AS-3000A supports the use of short lengths of coaxial cable for mast mounted equipment to dramatically reduce losses. Coaxial lines used in this type of system should be calculated and tailored so that they do not cause an impedance transformation. The connection of the transmitting equipment to the normally closed (NC) side of the AS-3000A relays allows the safe handling of high RF power without risk to the mast mounted preamp or LNA. Voltage is required to engage the normally open (NO) side of the relays for connection of the receive only preamplifier or LNA to the antenna. Removal of the voltage, or if power is lost, allows safe transmission without worry of equipment damage from transmitted RF, and keeps the preamplifier offline when the station is not used, for charge and pulse protection. See the linked documentation for detailed diagrams of system connections which typically require a sequencer, such as the SSB Electronic DCW2004B (ESB-1025), and an LNA, Mast Mount or separately enclosed.

SSB Electronic AS-3000 Two-Port Wideband Mast Mount Antenna Switch
SSB Electronic AS-3000 Two-Port Wideband Mast Mount Antenna Switch covers the entire range from DC to 3 GHz, featuring a low-loss SPDT coaxial relay. This model (ESB-5059) can switch two antennas to one feedline, or it can be used to switch between horizontal and vertical polarization on a cross-polarized Yagi or X-quad. Featuring high power handling, very low in-line attenuation and SWR, and simple 13.8 VDC operation, the AS-3000 is an excellent addition to any VHF, UHF or SHF station. The solid aluminum chassis incorporates a mounting bracket for a 1.5 to 2.3 in. mast clamp, with three downward facing Type-N female connectors, for the default normally closed (NC) port, a normally open (NO) port and the common port. A 4-pin DIN with mating connector is used for direct DC control of the relay, and a user supplied shielded control cable is recommended to prevent RF induced false keying. The AS-3000 supports the use of short lengths of coaxial cable for mast mounted equipment to dramatically reduce losses. Coaxial lines used with this switch and antennas should be calculated and tailored so that they do not cause an impedance transformation. Specifications of the AS-3000 Mast Mount Antenna System Switch (ESB-5059): Frequency range: DC – 3000 MHz Switch positions: 2 Insertion loss, typ.: 0.01 dB / 150 MHz 0.02 dB / 500 MHz 0.025 dB / 1000 MHz 0.03 dB / 2000 MHz < 0.1 dB / 3000 MHz Isolation: >60 dB / 2,5 GHz VSWR: <1.2 : 1 RF Power Handling, by band: 1000 W/2m; 800 W/70cm; 500 W/23cm; 250 W/13cm RF Connectors: Type-N female Direct DC Control Input: 4-pin DIN (mating connector provided) Switching Voltage: 13.8 VDC @ 250mA, max.
