DX Engineering Ferrite
DX Engineering Ferrites are partially magnetic metal and ceramic mixes available in a variety of forms, including toroid core, bead type and plastic-covered split-bead ferrite called snap-beads. They are used in a myriad of RF suppression applications to mitigate RFI (radio frequency interference) as well as to reduce pulse and other types of RF noise interference. Special ferrites are used for experimentation and electronic circuit building and for making transformers, RF chokes and antenna baluns. The variations of magnetic and non-magnetic metals and non-metal ceramics used to make ferrites are called "Mixes" and each has different radio frequency properties or ranges. Therefore, different mix number ferrites are typically used for different applications within those ranges, determined by decades of experiments by engineers and applications by hams. Each Mix has been assigned a color code to help identify the ferrite, so numerical labeling is not used on the metal. Color coded ferrite can be identified long after the numbered package is discarded or has disintegrated with time. How do they work? Simply use snap-on beads on a cable or wire. An even more effective choke takes a few to several turns of a wire or cable through and around a ferrite snap-on bead or toroid core. This mitigates RFI to, or from, the connected RF noise producing or noise affected electronic device. The results can be very surprising. Solving noise and RFI can be frustrating. Due to the nature of RF and noise interference suppression; the techniques of appropriate use of ferrites can take a bit of trial and error, but are often the best solution for a difficult problem. Use DX Engineering Ferrite for an incredible range of electronic circuits, noise abatement and RF suppression projects. The details of DX Engineering Ferrite mixes and types appear in each product description. Sizes and applications are discussed in "More Details" and in the literature available at the "Documentation" tab of each of these products.

DX Engineering Coaxial Connectors
The DX Engineering Coaxial Connectors shown here include two-part, silver-plated PL-259 and Type-N connectors designed to be crimped or soldered to the shield and soldered to the center conductor. These connectors deliver excellent performance for HF, VHF, and UHF applications. DX Engineering's PL-259 and Type-N connectors feature silver-plated brass throughout the outer and inner conductors and use PTFE dielectric—the best RF insulator—for very low loss and high electrical breakdown strength. Also available are DX Engineering Silver-Plated Reducers, which adapt standard solder-type PL-259 and Type-N connectors for use with single-shield RG-8X and RG-58U coaxial cables. While many types and grades of coaxial RF connectors are offered on the market, DX Engineering provides only top-quality connectors with silver-plated brass bodies and PTFE dielectric. These two-part solder-style connectors fit RG-213, RG-8U, RG-8X/LMR240 and other standard 0.405 in. single-braid shield coaxial cables intended for soldering*—but not 400MAX or LMR-400 double-shield cables. These solder-shield and solder-center connectors are the preferred choice for many Amateur Radio operators installing single-braid shield coaxial cables. Order your DX Engineering Coaxial Connectors and Reducers today! *NOTE: To prevent noise issues, modern engineering practice has determined that double shield cables that have one foil and one braid should not be soldered to the braid, including DXE-400MAX and LMR-400 style cables. Those cables should be terminated with crimp shield or clamp shield style connectors, also available from DX Engineering.

DX Engineering Receive Filter Plug-In Modules
DX Engineering Receive Filter Plug-In Modules provide frequency-specific receiving system enhancements, which fit into special DX Engineering devices listed below. These advanced plug-in filter modules are available separately to allow any user to create a specific or customized filter with low-pass, band-pass and high-pass frequency ranges. Filter cut-off and center frequencies correspond to the major Amateur bands, 160, 80, 40, 20, 15 and 10 meters, with filter module insertion loss of only about 1dB. By reducing or excluding frequency-specific interfering noise and signals, the noise floor can be lowered for the desired passband for dramatically improved reception DX Engineering Receive Filter Plug-In Modules may be installed in these devices: DXE-DMC-2 Dual Module Chassis accepts one or two filter modules to create a stand-alone passive inline filter unit of any configuration. One high pass and one low pas can be combined to create a multi-band bandpass filter of any HF range. DXE-RPA-2-PM Modular Receive Preamplifier accepts one Receive Filter Plug-In Module to customize the preamplifier passband. DXE-NCC-2 Receive Phasing Controller can accept one or two Receive Filter Plug-In Modules, one into each, Channel A and Channel B. The DX Engineering NCC-2 is highly regarded by many owners and engineers to be the best receive phasing and noise canceling unit available and is used extensively by enthusiasts in Amateur Radio DXing, Contesting, AM DXing, and Short-Wave Listening (SWL), and is also used in commercial AM and HF broadcast applications. DX Engineering Receive Filter Plug-In Modules add an extra dimension of functionality to the NCC-2, for advanced directional noise and signal nulling performance, enhanced with a specific frequency range operations. By default, NCC-2 internal option slots have bypass boards to pass all signals. Receive Filters placed into these slots dedicate the unit to filtered operation. Typically, one pair of band-pass or high-pass or low-pass filters, depending on desired filtering, is installed in the NCC-2 to suit the specific signal rejection needs of the discerning operator. As an example, an 80 meter DX enthusiast may elect to install two 80 meter band pass Receive Filter Plug-In Modules, part number DXE-R-BP80-PM, into their NCC-2 Channel A and Channel B middle slots. This dedicates their NCC-2 to 80 meter-only operations. This dramatically reduces noise and signals from outside the 80 meter band, very effectively excluding interference from nearby AM Broadcast, 160 and 40 meter stations. A much lower noise floor across 80 meters can help achieve reception of weak 80 meter DX signals. An additional pair of filters can be swapped out for a different band when desired. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. All Receive Filter Plug-In Modules displayed here are also conveniently listed on a single page linked in Documentation.

DX Engineering Exhaust Grounding Kits
Eliminate stubborn noise in your mobile installation with DX Engineering Exhaust Grounding Kits. Many modern vehicles have individual injectors and spark plug coils for each cylinder. These units can create substantial pulses on the vehicle wiring against the ground system. Engine blocks often have a poor ground, so anything attached to them can become a radiator. The exhaust pipe is directly bolted to the engine and can be excited just like an antenna, radiating the pulsing noise. By using one of our exhaust grounding kits, you can eliminate noise from your mobile installation. All hardware in these kits is made from high quality stainless steel. Each kit includes: * Exhaust saddle clamp * 14 in. long x 0.75 in. wide x 0.125 in. thick tinned copper braid * 3/8 x 1 in. bolt * 3/8 nut * Three 3/8 external tooth washers * 3/8 flat washer * 3/8 split washer
