Bushcomm OFO Wire Feeder Option and NVIS Kits
Want to enhance the lower-frequency operation on your antenna? Have a look at Bushcomm's open feeder kits. Bushcomm OFO Wire Feeder Option and NVIS Kits are open feeder options for most BBA Series Bushcomm HF antennas. Designed to complement their BBA (multi-wire) models and similar antennas, the OFO NVIS kits are easily constructed and attached to your existing Bushcomm multi-wire antennas. Lightweight and with low visual impact, OFO kits, when assembled, measure just over 10 meters in length. Bushcomm OFO kits are constructed with extremely durable composite-material spacers utilizing snap-lock wire holders, as well as quality stainless steel wire and fittings. OFO Kits are complete kits of most things necessary to install them yourself. Special OFO features: * Improved Performance on Lower Frequencies * Short Path NVIS improvement * Stainless Steel wire Installation kit contents: * 2 x stainless steel nuts * 2 x 10-meter lengths of stainless steel wire (with loops fitted) * 2 x stainless steel bolts * 2 x stainless steel washers * 6m cord (2 x 3m) * 10 x special Wire Snap-Lock Spacers * Instructions * Extra ferrules (in case of length adjustment) Mechanical details: Shipping Weight: 800 grams, 1.76 lbs. Length: 10 meters; 33 ft. Important Note: Works with BBA-100 series antennas when used in a horizontal configuration only (Not Inverted "V"). Not compatible with BBA-600 or BBA-1Kxx series antennas. Bushcomm offers many specialized wire antennas and wire antenna products. To enhance the lower frequency and NVIS performance of your BBA series antennas, order Bushcomm OFO Wire Feeder Option and NVIS Kits from DX Engineering.

DX Engineering USB Isolator
DX Engineering USB Isolator, DXE-ISO-USB is an inline Solid State device that provides surge protection between two USB 2.0 devices, typically a transceiver and a computer. The DXE-ISO-USB is a passive device that requires no power, and it has two ports, one USB A and one USB B. It is bi-directional, so it can be installed in either direction. The supplied USB A to USB B standard patch cable, 19.7 in. (500mm), can be reversed and used for either type of equipment connection with the opposite connector to the mating port on the ISO-USB. A user supplied cable must have the opposite mating connector for the ISO-USB and its other end must have the USB connector type that provides connection to the second piece of equipment or computer. Often, an identical USB A to USB B will be on hand or is readily available. USB interface cables between several types of equipment can serve as a conduit to lightning pulses or other unexpected voltage pulses. For example, a damaging surge can occur whenever one device is connected to an antenna feedline that also has a USB cable to the other device, which is connected to a commercial AC power main, or through a DC power supply. The DXE-ISO-USB protects a transceiver from a voltage surge coming from the computer, and vice versa, it protects a computer from a surge from a transceiver. The maximum USB 2.0 speed of the DXE-ISO-USB is 480 Mbps (Mb/s). This supports RS-232 COM port data speeds greater than the fastest 115,200 bps baud rate selection found in most USB capable equipment. PLEASE NOTE: The DXE-ISO-USB does NOT support USB C Gb/s data speeds, and it does NOT pass sufficient DC current for charging or powering a device. Maximum current is 100mA (0.1A). It cannot be used for data storage devices and is not to be used for charging. In an unusual application, two different user supplied cables, USB A to USB C and USB B to USB C, could be used to provide DXE-ISO-USB protection between two USB C devices, as long as neither device is supplying or drawing power.

DX Engineering Pretuned Quarter-Wave Phased Array Cables
DX Engineering Pretuned Quarter-Wave Phased Array Cables are ready to go into your phased array for 80 or 40 meters. These RG-11U coaxial cable assemblies are electronically tuned during production to 3650 kHz and 7100 kHz, the two most popular phased array frequencies. Pretuned Quarter-Wave Phased Array Cables ensure optimum pattern control and gain from your phased antenna array. They are available individually, in pairs and in four-packs, all terminated with soldered silver-plated PL-259s. These cable assemblies are exactly as required for many 80 and 40 meters phased arrays including Comtek Hybrid Four Square Arrays, DX Engineering TFS4 Four Square Arrays, as well as DX Engineering Dual Vertical Arrays. DX Engineering Pretuned Quarter-Wave Phased Array Cables are made from the highest quality waterproof PE jacketed, direct-burial RG-11/U 75-ohm low-loss foam coaxial cable. They are called "phasing feed-lines" because they are one quarter wavelength long electrically, which differs from the free-space dimension by the velocity factor of the cable. This RG-11U coaxial cable is manufactured to DX Engineering specifications, with a nominal velocity factor of 0.82. That means they're the right physical length to allow for easy burial and routing from the center-mounted array phasing unit to the base of each vertical element. Maximum performance is achieve with properly installed phased arrays, including ground-mounted base-fed full-size quarter-wave elements with free-space array dimensions and complete, interconnected ground radial wire systems. The electrical dimensions of phased array transmission cables are critical to system performance. Each of our cable assemblies is hand crafted and electronically tuned at DX Engineering. Eliminate the trouble and concern of trying to tune your own cables and order a set of DX Engineering Pretuned Quarter-Wave Phased Array Cables. NOTE: Custom tuned phased cables for all other frequencies in each Amateur band are also available. See DX Engineering Phased Array Quarter Wave Tuned Cables.

DX Engineering Phased Array Quarter Wave Tuned Cables
DX Engineering Phased Array Quarter Wave Tuned Cables ensure optimum pattern control and gain from your phased antenna system. These cables are custom built to your array frequency, made with the highest quality waterproof PE jacketed, direct-burial RG-11/U 75-ohm low-loss foam coaxial cable and terminated with silver plated PL-259s. From the system phasing unit to each array element, these phasing feed-lines are one quarter wavelength long electrically, which differs from the free-space dimension by the velocity factor of the cable. The electrical dimensions of these cables are critical to system performance. These cables, manufactured to DX Engineering specifications, have a nominal velocity factor of 0.82, providing plenty of physical length for easy burial and routing from the base of the vertical to the center-mounted controller. DX Engineering Phased Array Quarter Wave Tuned Cables are custom built by DX Engineering. Each is hand crafted and electronically tuned to a specific HF frequency. Typically, they are tuned to the same frequency as the antenna array. After placing your order for DX Engineering Phased Array Quarter Wave Tuned Cables, please inform us of the order number and your array frequency for your tuned cables by e-mailing dxengineering@dxengineering.com or by calling 800-777-0703 or 330-572-3200. You may leave a message after business hours. Custom cable assembly orders will process after we receive your frequency information. Please contact DX Engineering Technical Support if additional assistance is needed. We will contact you if we have any questions about your special order.
