DX Engineering Heavy-Duty Saddle Clamps
Our tradition of continuous innovation was evident with the introduction of the DX Engineering Heavy-Duty Saddle Clamp line. DX Engineering set new standards over a decade ago with the introduction of the industry's best clamps for mounting antennas and element tubing. Featuring superior gripping power, our new Heavy-Duty Saddle Clamps are available in six different sizes, to fit tubing with Outside Diameter (OD) inch sizes of 0.75, 1.00, 1.25, 1.50, 1.75, and 2.00. Commercial and industrial engineers and installation technicians all over the world have discovered a diverse range of applications for DX Engineering Heavy Duty Saddle Clamps. DX Engineering Heavy Duty Saddle Clamps are designed to be used where maximum torque handling is required on aluminum, steel or stainless steel tubing. Conceived of by builders of large and heavy Yagi antennas and Log Periodic arrays, these clamps are made in sizes that securely fit the outside diameter of tubing for mounting to a flat plate or surface. Their wide gripping surface equals superior clamping power! Perfect for antenna construction and mounting, or wherever standard U-bolt saddle clamps and other torque-control products have proven inadequate, our Heavy Duty Saddle Clamps provide excellent grip on booms, masts and element tubing. Unlike stamped or machined-type clamps, Heavy Duty Saddle Clamps are cast from a rugged aluminum alloy that grips tubing with a special textured surface and are sized for an incredibly secure fit that resists torque, wind and weather. Heavy Duty Saddle Clamps include two cast aluminum saddles (two halves) and a stainless steel reinforcement plate for high strength and superior corrosion resistance. Due to the wide diversity of clamping applications where Heavy Duty clamps are beneficial, mounting hardware is NOT included. However, a complete line of Armor-Coated and Stainless Steel Hex Bolt Hardware Sets are available for top performance in most mounting applications. Typical Heavy Duty clamp mounting applications on a 1/4 in. plate require a minimum length bolt set, as indicated in the chart, linked in "More Detail…," and displayed in the "Required Parts" tab. For larger tubing attachment applications with ultimate gripping strength, DX Engineering Super Duty Saddle clamps are also available for 2.0, 2.5 and 3.0 in. O.D. sizes. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Plan your next project with the best clamps available... period. DX Engineering Heavy Duty Saddle Clamps are ready to provide superior performance for your antenna, mast or other tubing mounting application.

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.
