74 Remote Antenna Radio Switches DX Engineering uses a symmetrical design in these switches to ensure excellent reliability and performance. Installation is easy too. Simply use the switch’s external control cable connector to attach your CAT-5 cable to the controller in your shack. These switches provide great SWR and superior port-to-port isolation—better than 60 dB for ALL ports, not just the best port. You'll see 70 dB (HP) and 60 dB (SD) in worse-case scenarios. That's the highest port isolation of all the major-brand coax switches we’ve tested. They’re fully RF-shielded with a UV-resistant cover, and have built-in lightning protection. The unused antenna ports can be jumpered for open control line with no disassembly or they can be easily shorted to ground. High Performance (HP) and Severe Duty (SD) Options The DXE-RR8B-HP uses 16 relays (2 per port) in a star arrangement to provide greater than 70 dB of port-to-port isolation. It is designed to switch coaxial lines in RF systems operating up to 5 kW continuous duty. The DXE-RR8B-SD is the largest switch in the RR8B series, designed to switch coaxial lines in high power RF systems up to 10 kW continuous duty.

All control signals are RFI filtered as are all VE2DX printed circuit boards with shielding on both sides. Each SO-239 antenna port features five relays to achieve a design with over 80 dB of port isolation and full legal-limit power handling. Built into a weatherproof chassis (11" W x 7.75" H x 4" D), the switch's simplistic design allows the use of only two coaxial cables from the station to the tower. Both radio inputs have access to any of the unselected six antenna outputs. Switches may be controlled by third-party switch consoles, station controllers, and computer automation. Available in 12 and 24VDC versions. VEX-2X6AS-12 2X6 Antenna Switch, 12VDC ....................................................$624.99 VEX-2X6AS-24 2X6 Antenna Switch, 24VDC ....................................................$624.99 Antenna & Radio Switches Band Decoders These straightforward automatic band selection units from VE2DX monitor CAT information from your radio and, based on your settings, select the proper remote switch selection for your frequency. Relay outputs remotely control antennas or band pass filters. They can be connected via CAT TTL cable, Bluetooth, WiFi, USBoBT, et. al. Models support Elecraf , FlexRadio, Icom, Kenwood, Yaesu, and other manufacturers. The relays can be ground, internal 12VDC, or external 12VDC controlled. Choose from three models: • BD1-BT: Single-radio/single-switch output band information decoder with eight relay outputs • BD1-BTPLUS: Single-radio/dual-switch output band information decoder with two sets of eight relay outputs • IBD2-BT with SDI: Dual-radio/dual-switch output band information decoder with two sets of eight relay outputs. SDI (Sof ware-Defined Interlock) monitors the two radio frequencies, and if one radio selects a band already used by the other radio, it prevents the IBD2-BT from selecting that output via LED alarm/buzzer, or buzzer or CW sequence for blind operators. All models include heavy-duty multi-layer shielding of the PCB and enclosure, plus RFI filtering of all signals, power sources, and grounds.
