DX Engineering Multi-Band Dipole Antennas
DX Engineering Multi-Band Dipole Antennas are designs that are rugged, yet lightweight. Using a tuner, they are usable to 30 MHz and come complete with the wire elements, ladder feedline, center T support, and end mount brackets. These antennas are built using the highest quality components. They use 14 AWG stranded-copper, PVC jacketed elements for flexibility and strength and 100 ft. of 18 AWG 300-ohm 0.88 Velocity Factor ladder lines that are UV-resistant. Stainless steel hardware is included. Often, a 4:1 balun is suggested for multi-band dipoles; however, the best balun to use for this application is a 1:1 ratio. The 1:1 baluns provide better balance, have lower loss, and are more tolerant to load impedance and balance variations than other baluns. A tuner balun is not included in the dipole antenna kits and is available separately. The dipole center T support has pre-drilled holes for the attachment of the wire elements, feedline, and support or messenger lines. The center support top hole is used for the attachment of a "messenger line" that can be strung above the antenna wire and is used to provide support for the antenna wire and feedline. The use of the messenger line, which is strongly recommended but not included, will reduce the stress on the element wires and keep the antenna from stretching over time, which will change its resonant frequency. This line can be thin Synthetic Textile rope available from DX Engineering, which has a high breaking strength. Ideally, it should attach to the same structure used for the dipole, only above it, forming at least a 30 degree angle between the dipole and the messenger line. For further information and to decide the amount of rope you will need, please read the included instructions and check your wire antenna area of construction. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. When you lack the room for more than one antenna or need a multiband antenna for band agility, consider one of these DX Engineering Multi-Band Dipole Antennas as an elegant and economical solution!

DX Engineering Replacement TW Antenna Structures
DX Engineering Replacement TW Antenna Structures are direct-replacement structures for the top (DXE-TW-BAS-TOP) or bottom (DXE-TW-BAS-BTM) of your DX Engineering TW Adventurer, Explorer, Globetrotter or Solo Explorer compact vertical dipole antennas. No one ever wants their antennas damaged, but accidents do happen; especially with antennas as portable as these TW Series antennas. Made of high-quality black powder-coated aluminum, these replacement parts are also compatible with older TW portable or stealth antennas. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. If you have need of a replacement top or bottom section of your TW antenna, order DX Engineering Replacement TW Antenna Structures and get your TW antenna back in great shape! NOTE: Some older versions of the TW Antennas are not compatible with current production parts. The original manufacturer of TW Antennas had changed the design more than once and newer parts will not fit some older models. Call DX Engineering to verify if your old TW Antenna will be compatible with currently produced parts and assemblies.

DX Engineering Active Receive Vertical Replacement Tubing
DX Engineering Active Receive Vertical Replacement Tubing, model DXE-ARAV-A, is provided for those who might need to replace damaged or lost aluminum tubing for their current model DXE-ARAV4 series Active Receive Vertical antenna. This is NOT the Retrofit Kit. For the conversion of older Active Receive Verticals, see the DXE-ARAV-R which includes a new mounting plate and tubing element. This DXE-ARAV-A kit contains the three 36 in. aluminum sections, 1/4, 3/8 and 1/2 inch, as well as a complete set of new stainless steel element hardware. The required Allen wrenches are also included. The assembled length of this replacement element is 8 feet 6 inches, the same as the original. Refer to the original manual for the DXE-ARAV4-1P, -2P, -4P and -8P for assembly details. The manual is linked at the documentation section at the parts detail web pages.

DX Engineering Bead Choke Standoff Kits
DX Engineering Bead Choke Standoff Kits bring a practical solution to a serious problem when ferrite chokes are placed directly onto the metal boom at the feedpoint of beam antennas. A number of Amateur Radio operators and antenna engineers have known for years about the superior choking function of many ferrite toroids beads placed directly on the coaxial cable, as compared to standard feedpoint baluns. A more recent revelation is that the proximity of ferrite beads on coax taped to the aluminum boom of the antenna drastically reduces their effectiveness. DX Engineering Bead Choke Standoff Kits are mounting systems, made of fiberglass or acetyl standoff rods (color varies), PVC carriers and stainless steel hardware, available in four versions. Two sizes of PVC cradle tubes handle two different types of RF bead chokes; 3/4 inch outside diameter (OD) ferrite beads on RG-400 size cable, and 1 inch OD ferrite beads on RG-213 size 0.405 in. coax cable. Each are offered with two different boom size clamps, 2 inch OD and 3 inch OD. Bead Choke Standoff Kits simply hold an RF bead choke and feedline 4 inches away from the metal beam antenna boom (or 4 inches away from the metal mast for a dipole). They maintain the optimal choking performance of ferrite beads on coax. Using DX Engineering Bead Choke Standoff Kits, ferrite bead chokes function at peak performance for these key results: • Prevent feedline radiation of RF • Preserve current balance for proper beam antenna pattern • Prevent feedline shield exterior collected noise and signals from entering the antenna and interior of the feedline, resulting in lower noise floor and enhanced reception The absolute superiority of RF chokes made of many beads on the feedline, over the traditional enclosure balun, is becoming better understood in Amateur Radio. They achieve the best possible RF isolation of the feedline from the antenna and provide completely balanced currents at the feedpoint. Plus, they provide quieter reception with reduction of common-mode noise. Keeping Bead RF Chokes away from metal preserves the optimal function of this method of antenna feedpoint current balance and isolation. This mechanical requirement is simple and practical with DX Engineering Bead Choke Standoff Kits.

DX Engineering Boom Element Plates
DX Engineering Boom Element Plates are used to build long-boom monoband directional antennas for the standard bands, 20 through 6 meters. They are made from a very strong 3/8 in. thick insulating material, each predrilled for specific DX Engineering saddle clamps and sized dependent upon band and element type, driven or parasitic. They accommodate the mounting of aluminum antenna elements to a 3-inch boom for special beam antenna kits. This series of insulated plates have no hardware; they are component parts used in the DXE-EBB Element to Boom Bracket Kits which include one plate and the appropriate sizes and number of saddle clamps, depending upon band and element type. DX Engineering Antenna Element Tubing Kits, Element to Boom Bracket Kits, and Antenna Boom Tubing Kits are each sold separately.
