Alpha Delta Coax Switches
Alpha Delta Coax Switches have a precision-machined switch shaft and quadrant mechanism for more accurate and stable switching performance. These switches have a low-loss micro-strip cavity design, positive detent switching, master antenna ground function, a front panel removable arc-plug surge protection module, and excellent HF through UHF performance. The unselected antenna ports are grounded for protection and maximum isolation. Alpha Delta Coax Switches are used worldwide in government, military, and commercial applications and are manufactured in Alpha Delta's ISO-9001 certified production facility in the USA. They come available with either a 2-port or 4-port position, and both have the option of either the UHF female (SO-239) or N female connector. These switches are all built into the same heavy-duty chassis that is 5.250 x 3.500 x 1.250 in. (WHD), excluding connectors and knob. Note: When placed in the "COM" position, all switch positions are grounded. When a port is selected, that port is ungrounded while all other ports remain grounded. Additional features include: * Higher strength, lower resistance sliver bearing solder * Durable abrasion resistance with powdercoated finish * Brass arc-plug housing for improved gas tube positioning Note: When available, please look at the files under the "Documentation" tab for additional product information.

Daiwa CS-401 Four Position Coax Switches
Daiwa CS-401 Four Position Coax Switches feature clearly arranged input and output connectors for easy identification of connection positions and supports DC to 500MHz operation. It features four SO-239 output ports with a unique switching mechanism that ensures over 60dB isolation at 200MHz and grounds inactive antenna ports for enhanced safety. The CS-401 offers a maximum power rating of 2.5kW PEP (1kW CW), 50-ohm impedance, and less than 0.2dB insertion loss. The inactive antenna ports are always grounded to ensure stable and efficient switching. If any of the four positions are unused, selecting that port during a thunderstorm can help protect the radio from lightning-induced surges. However, note that a direct lightning strike to the connected antenna may still cause damage.

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. (85 x 135 x 70 mm) Weight: 0.22 lbs. (0.1 kg)

EA4TX RemoteBox Universal Antenna Switch Controllers
EA4TX RemoteBox Universal Antenna Switch Controllers are extremely versatile devices that provide automated control of remote antenna switches of many designs. Local and remote control antenna selections are supported with PC software via USB and with band data interfaced transceivers. Specific RemoteBox models are available to control several different remote antenna switch configurations. They work with one-of-eight DX Engineering DXE-RR8B-HP and DXE-RR8B-SD (1x8), the two-of-eight DXE-RR2X8B (2x8), several different brands of 1x6, 1x8, 2x6 and 2x8 as well as a specially configured RemoteBox to control a 4-element phased array, such as the Comtek Four Square. The EA4TX RemoteBox controller replaces the remote antenna switch manual controller and may be operated by free software and by band data interface cable. The specially produced EA4TX freeware Windows program is called RBM--RemoteBox Manager. It is provided on the included CD-ROM and is also available by download. It accommodates PC local or remote control and band data setup selections. The RemoteBox front panel LCD displays programmable antenna names and facilitates manual selections. Automatic antenna selections are programmed with the software. The RBM program can also read and analyze messages from Win-Test and N1MM networks, providing centralized control of SO2R and Multi-Two contest operations. The RemoteBox will not allow the selection of the same antenna on both radios of a two radio system. The EA4TX RemoteBox is not a simple antenna switch controller. Since it can be controlled by a computer, it is the perfect choice for Remote Antenna control. A user supplied micro-PC can interface for Internet control. In addition, with transceiver band data interface cables in place, the RemoteBox reads the selected band and automatically switches to the correct antenna. This type of simplified station automation eliminates the possibility of human errors. Band Data input is supported by user built cables; a single cable for 1x4, 1x6 and 1x8 models and two cables for 2x6 and 2×8 models. Connected transceivers automatically select the correct antenna by assigned band memory. Software selection of Yaesu or Elecraft BCD for any HF band, or ICOM voltage band data for major bands, is supported. The EA4TX RemoteBox Manager software zip file download is linked on the detail page. Click "More Detail" below for additional information about this innovative antenna switch control system. Bring new functionality and flexibility to your station with easily implemented automation and computer control of your remote antenna switches.

4O3A RS3000 Reversible Switch Controllers
4O3A RS3000 Reversible Switch Controllers are designed to improve the safety and efficiency of the RS3000 2x2 Reversible Coaxial Crossover Switch system. They ensure switching between radios and antennas only occurs when neither connected radio is transmitting, preventing accidental switching if one user begins transmitting while the other is still on the air. This makes it ideal for SO2R (Single Operator, Two Radios), MS (Multi-Single), or M2 (Multi-Two) contest configurations. These switch controllers operate on 13–15VDC input. A 3-pin DC output (5.08 mm pin header) connects to the RS3000 Crossover Switch. Before use, connect the PTT lines from both radios to the controller's RCA jacks. The controller connects to the RS3000 switch via the +12V/GND terminals. If a user attempts to switch while the other is transmitting, the controller delays the switch until the PTT line is inactive. During this delay, the "Wait" LED is illuminated. This ensures safe switching regardless of transmission frequency.

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.
