DX Engineering Aluminum Tubing
DX Engineering High-Strength Aluminum Tubes are ideal for your antenna building projects. It is made available in sizes that fit into and over the next, with close tolerances specifically designed for strength when joined and overlapping only by a few to several inches, to build Yagi, Moxon or vertical antenna elements. NOTE: This tubing is NOT intended for each size to telescope completely into the full length of the next; it cannot be used for telescopic mast building. DX Engineering aluminum tubing is manufactured to very close tolerances. This provides the greatest amount of surface contact between nesting tubes for mechanical and electrical stability. Due to the close tolerance, any burrs, dirt, grit or other foreign material, as well as dents, dings and unseen bending or crushing suffered during shipment will cause binding that prevents this aluminum tubing from fully nesting. 6063-T832 seamless drawn aluminum tubing is available in 3, 6 and 12 ft. lengths. 6063-T832 tubing provides good resistance to general corrosion, including stress corrosion cracking, and an excellent surface appearance. Use a series of 3 ft. lengths to build an element that tapers more quickly for lower wind-resistance applications. Use a series of 6 ft. lengths to make an element that tapers more slowly for greater strength and bandwidth. The 12 ft. lengths are great for HF Yagi construction. Most sizes (except 12 ft.) are available slit on one end for use with DX Engineering stainless steel element clamps. If un-slit ends are required for your applications, merely insert the slit end into the next larger size in the stack and use your own attachment method. 6063-T832 tubing features a 0.058 in. wall thickness and is available in 1/8 in. increments from 3/8 in. to 2-1/8 in. O.D. 3003-H14 drawn aluminum tubing features a 0.035 inch wall thickness and a 1/4 inch outside diameter. Each piece is supplied with non slit ends and is available in both 3 foot and 6 foot lengths, making them ideal for your antenna building projects. If your setup requires maximum strength at very long assembly lengths, then choose DX Engineering 6061-T8 tubing. This heavy-duty version features a 0.120 in. wall thickness and is available in 1/4 in. increments from 1-1/2 in. to 3 in. O.D. Packaged shipments of 6 ft. tubing have oversize shipping fees, regardless of the number of 6 ft. pieces. Therefore, order more 6 ft. pieces to spread oversize fees over more tubing for a more cost effective shipment. Tubing that is 12 ft. long MUST be shipped by truck freight. If you need many pieces of the same size in a 12 ft. tube length, then buying DX Engineering High-Strength Aluminum Tubing Bundles (elsewhere in our catalog) maximizes the economy of scale for your shipping costs.

Anderson Power Products® DC Power Connectors
Powerpole® Connectors with Plated Silver Contacts maximize performance and reliability by offering up to 10,000 mating cycles before failure. They are even recommended for circuit interrupt or hot-plug applications. That means you won't have to shut down your shack supply every time you want to disconnect a peripheral device. Powerpole® Standard Housings allow you to color code, or just change the color of, your Powerpole® connectors. Their standard housings are available in a wide array of colors. The metal Power Contacts are not included with these housings, but are available separately. These standard housings will not mate with the finger-proof housings. Powerpole® Ultrasonically Welded Standard Housings feature connector housings that are ultrasonically welded to create a one-piece connector unit using an APP® special process. After welding, retaining pins are no longer required to secure the stacked housings to each other. This allows Powerpole® 15-45 connectors to be used as durable one-piece connector headers. Retention clips prevent Powerpole® 15-45 blocks from unintended disconnection. They feature a small finger tab for easy insertion and removal. Once your Powerpole® connection has been made, inserting a retention clip will keep the connection from easily pulling apart. Organize and connectorize! Get rid of rats nests and tangled inefficient power connections. Order Anderson Power Products® DC Power Connectors from DX Engineering!

DX Engineering Fiberglass Tubing
DX Engineering Fiberglass Tubing is ideal for building your own antenna supports, such as quad spreaders, insulated UHF stacking frames, a vertical wire, or even temporary push-up masts using the larger diameter tubing. DX Engineering Fiberglass Tubing features a soft gray color that is uniform from piece to piece to make an eye-pleasing assembly and is finished to be highly UV resistant. Optional slit ends are ideal for clamping without drilling, because drilling weakens the tubing. Don't forget DX Engineering stainless steel element clamps for that final, long-lasting assembly or easy-to-assemble portable installation. DX Engineering Guy Rings and Vertical Guying Kits are available to stabilize a vertical assembly. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. These fiberglass tubes are non-telescopic, sold as-is, and non-returnable. Please contact us with questions before purchasing. Uses for our DX Engineering Fiberglass Tubing are only limited by imagination. Kick your thoughts in gear and order your tubing… today!

Yagi Antennas Explained
Yagi Antennas have become commonplace in amateur radio since their invention in the 1920s by Shintaro Uda and Hidetsugu Yagi. These directional antennas, consisting of two or more parallel resonant antenna elements, provide—as radio amateurs know—great performance across a variety of bands. If you've ever wanted to build and experiment with Yagi beam arrays then "Yagi Antennas Explained" is for you. The 208-page paperback is a practical guide to the design, operation, and construction of Yagi beam arrays for the amateur bands from 20m to 70cm. Rather than using mathematics, where possible, explanations are used to describe the operational aspects of beam arrays. So you'll find explanation of gain, front to back ratio, feed point impedance, polarization, radiation pattern, and bandwidth. Antennas need to be connected to the radio equipment using feeder cables; therefore, the feeder cables are reviewed, along with the techniques utilized to match a feeder cable to an antenna. Practical techniques for construction are offered in abundance, with the emphasis placed on using hand tools and materials that are generally available. Many practical designs are included, ranging from a 15m band 2-element beam, through to a 70cm band 19-element Yagi. Installations are also covered, including how performance can change as height-above-the-ground increases –and the effect of mounting several Yagi beam arrays on the same mast. The final chapter describes techniques where Yagi beam arrays can be combined to produce specialized antennas. This includes how Yagi beam arrays can be stacked or bayed. A method is described where two Yagi beam arrays can be combined to produce a dual-band antenna fed using a single feeder cable. Other examples include how two Yagi beam arrays can be combined to produce a circularly polarized beam antenna suited to use when the distant station's polarization is uncertain. If you want a practical and understandable guide to the fascinating world of building, operating, and experimenting with beam arrays from 20m to 70cm, then "Yagi Antennas Explained" is certainly the book for you.

DX Engineering Receive Device Replacement Parts Kits
DX Engineering Receive Device Replacement Parts Kits contain RF chokes and capacitors that are commonly found in bias tee circuits and in many other receiving and control devices. Also known as feedline voltage injectors, bias tee circuits occasionally suffer minor lightning pulse damage. Typically the choke or capacitor is burned out, which can be easily repaired with one of these replacement parts. Contained in each kit are 30 electronic components: • 10 each 100uH RF chokes • 10 each 0.1uF 50V capacitors with 0.2 in. leg spacing • 10 each 0.1uF 50V capacitors with 0.3 in. leg spacing. Click "More Detail" to see the DX Engineering device compatibility chart. Several DX Engineering devices use only one of these parts. None of the devices listed require all three parts; this is a multi-purpose package for the repair bench. These common electronic parts may be used for many other projects around the shack and in station gear, and even for repair of other types of equipment. Use these parts at your own discretion. Technical support for any application is not included.
