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.

Par EndFedz® Antennas
Par EndFedz® Antennas are End Fed Half Wave (EFHW) antennas with the match box coax connection at the end of the wire, for convenient and quick stealth portable operations. These single-band and multi-band antennas can be mounted horizontally, vertically, or as a sloper. No ground plane or counterpoise is needed so portable operation could not be easier. Simply hang the far end from a tree limb or send the wire out a hotel room window or balcony. You can use a telescoping fiberglass mast to get the antenna really high in the air and the supplied end insulators the installation easy. Stealth operation in CC&R and HOA antenna restricted locations is simplified. Their all-black construction makes them difficult to see. Each Par EndFedz® features a UV-resistant black ABS plastic housing with a support rope attachment hole that encloses a matching network to allow the antenna to be fed with standard 50 ohm coaxial cable with a PL-259 (UHF male). All hardware is stainless steel and the SO-239 (UHF female) connector is silver plated and has a PTFE dielectric. The antenna wires are either 18 or 26 AWG stranded Copperweld® with 200 pound breaking strength and a tough, 100% UV stable black polyethylene jacket. One end of the antenna wire has a #10 solder lug making attachment to the matching network feedpoint simple and easily replaceable, if necessary. Standard single and multi-band versions handle 100 or 200 watts and higher power versions handle 300 watts. Lightweight QRP PolyStealth models handle 25 watts and are ideal for portable operation because they are lightweight; the MKII model weighs only 8 ounces and the Trail Friendly model weighs only 3.5 oz. Par EndFedz® Antennas require no counterpoise or extra conductors. The EF-ALLBAND-KW model, about 133 ft. in length, covers eight bands, 80 through 10 meters. The ALLBANDKWJR is 74 ft. in length and operates on five bands, 80-10 meters. The 64 ft. EF-40-10-KW operates on four bands. All three models handle up to 1000 watts SSB/CW and 250 watts AM/Digital Modes. The need for an external tuner may vary based on the antenna model selected and the desired operating band. The manufacturer refers to these antennas as "End-Fed Dipoles" based upon the assertion that a "half-wave radiator is a dipole." This is a variant of the classic definition of a dipole which is a center-fed antenna with two radiating legs running in opposite directions from the feed point. Additional claims about the EFHW state that end feeding a half-wave "can energize the radiator 'nearly' as well as a center-fed." Recent anecdotal measurements indicate that the EFHW radiates about 70% as well as a traditional center-fed dipole. More information is available at each Par EndFedz® model listed below.
