DX Engineering NCC-2 Receive Antenna Phasing Systems

Imagine adjusting the controls to knock out strong interfering stations or noise—and then being able to copy and log that weak DX station. By successfully combining the right antennas with the advanced phasing capabilities of the NCC-2, this is the operating thrill that every radio enthusiast can enjoy, again and again! DX Engineering NCC-2 Receive Antenna Phasing Systems are variable phasing controllers that combine the 300 kHz- 30MHz received signals from one transmit antenna and one receive antenna, or from two dedicated receive antennas. Combining signals from two stationary antennas physically spaced 1/10 to 1/2 wavelength apart creates an array pattern with signal peaks and dips called nulls. Adjusting the NCC-2 Phase and Balance controls have the effect of electronically rotating or steering that pattern. Steering the null direction to significantly weaken a local or distant interfering signal or noise is known as "Noise Cancelling." This "Noise Cancelling Controller" (NCC-2) can dramatically enhance the reception of weak signals from non-null directions. This "reverse-beam" capability on radio frequencies AM Broadcast through HF can provide amazing benefits for many types of AM DX and SWL receiving and ham radio operating. Work new DX, hear the weak station in casual regional conversations, snag the rare multiplier in contests and hear beyond the noise and interference in dire circumstances. DX Engineering NCC-2 Phasing Systems now feature the built-in RTR Receive-Transmit Interface relay system that expands the exciting benefits of antenna phasing for interference reduction in two ways: * First, the NCC-2 can combine signals from the HF transmit antenna and a separate receive antenna to effectively notch-out strong stations or noise. Almost any Amateur can now enjoy the benefits of antenna phasing and noise-nulling, even those with space limitations for separating the receiving and transmitting antennas. * Second, the user of any standard HF transceiver that lacks a separate receive antenna input can have enhanced reception of noise and signal nulling with the DXE-NCC-2 and two antennas. Rear panel SO-239, F and BNC connectors make the NCC-2 extremely versatile and easy to connect to almost any receiver or HF transceiver up to 200 watts. Redesigned with plug-in modular circuit board sockets, the NCC-2 includes one switched and powered internal slot and two passive internal slots per channel to accommodate these new options: * DXE-RPA-2-PM Receive Preamplifier Plug-In Modules (powered): one per channel for low-signal passive antennas with poor ground conditions * DXE-RG5000HD-PM Receiver Guard 5000HD Plug-In Module (passive): Front-end protection for the NCC-2 and the receiver * DXE-IT-PM 75 to 50 ohm Impedance Transformer Plug-In Module (passive): to match 75 ohm RX ANT feedlines to NCC-2 50 ohm internal impedance * NCC-2 Receive Filter Sets (passive, non-switchable): High Pass, Band Pass and Low Pass Filters for 160, 80, 40 meters typically in stock, with other band filters available individually by special order. DX Engineering NCC-2 Receive Antenna Phasing Systems offer these new additional benefits: * Multi-Color Status Indicating LEDs for Power, RTR Mode and Preamp Power CH A and CH B * New Radio Key Line Input with RX Enable Output-RTR Failsafe to prevent RF damage to NCC-2 and RX equipment * New ACC Key Line Output RCA female 'ground on transmit' pass-through for Amplifier or Accessory * New screw-on 2.1mm DC connector to prevent accidental power cable pull-out * Operates on +13.8VDC @ 2A input to power the NCC-2 and internally jumper set Bias Tee on each RX ANT ports for coax fed Active Verticals and other accessories.

DX Engineering 450 Ohm Ladder Line

DX Engineering 450 Ohm Ladder Line is a transmitting grade low-loss parallel-wire RF feedline featuring a strong, waterproof, UV black polyethylene insulation. To maintain the wire spacing between the conductors while reducing losses, the integral flat plastic material alternates with rectangular openings, which explains the "Window Line" nickname. Capable of handling over 3 kW of RF power, DXE-LL450 is a very low-loss transmission line across HF. It is ideal for exceptionally long feedline runs and for low band wire antennas operated on multiple bands on which the feedpoint impedance can vary significantly, causing mismatch and elevated SWR. Unlike coaxial cables, DX Engineering DXE-LL450 Ladder Line maintains low RF losses at frequencies where antenna feedpoint impedance mismatches cause high SWR. It can provide significantly higher efficiency than coaxial cable when feeding non-resonant antenna systems that are matched with a wide impedance range antenna tuner. DXE-LL450 450 Ohm Ladder Line is a high-quality flat RF feedline, about 0.938 in. wide (15/16") with two 16-gauge copper-clad steel wire conductors (29 AWG x 19 strands) that provide the strength to hold up for long spans between supports without twisting. It exhibits a nominal impedance of around 400 Ohms and a nominal Velocity Factor of 91 percent. For proper performance, LL450 Ladder Line must be installed suspended through the air supported by insulators every 25 ft. or less, kept at right angles and several inches away from other wires, and at least one foot away when run parallel to the earth or large metal surfaces. Installing with an axial twist of one turn per 10 ft. can reduce wind, rain and ice loading, RF coupling and RF noise. DXE-LL450 can be mounted with insulators and suspended on metal or wood posts or run along a wood fence line, only if the fence has no wires or metal mesh that couples RF noise or unbalances the feedline. Often used for non-resonant wire doublet antennas, DXE-LL450 can be more easily terminated outdoors to a DXE-MC20-C4-1 4:1 Balun or a DXE-MC20-1-1T 1:1 Balun. Then, with no inline switches or relays, directly connect the antenna system to a typical indoor wide range antenna tuner using a solid dielectric coax, not foam dielectric, to handle high voltage at high SWR. DXE-213U or DXE-214 Coaxial Cable Assemblies 12 or 18 ft. with PL-259s are perfect for this method, which eliminates the need for a special balanced tuner, and avoids the losses and detuning effects caused by unbalancing when ladder line is routed indoors near wires and ducts. DXE-LL450 is sold by the foot, previously sold as DXE-LL450-CTL, this is the same ladder line with a new part number. It is also available in spools of 500 ft. DXE-LL450-5C and 1,000 ft. DXE-LL450-1K, which are specified for DX Engineering Reversible Beverage System Antennas. NOTE: This type of feedline is intended for MF and HF use and is not suitable for use above 54 MHz. Also consider DX Engineering 300 Ohm Ladder Line, DXE-LL300, an excellent alternative low-loss HF feed line that reduces impedance extremes on non-resonant HF multiband antenna systems.

DX Engineering Receiver Guard Electronic RF Limiters

DX Engineering Receiver Guard RG5000HD Electronic RF Limiters are the best choice of inline devices to protect your receiver antenna inputs. The Receiver Guard is a receive antenna input limiter specifically designed to protect a sensitive receiver front-end against high levels of RF and potential damage. At the heart of each Receiver Guard is a highly effective electronic RF limiter covering 500 kHz to 150 MHz with an insertion loss under 0.15 dB up to 50 MHz and under 0.30 dB up to 150 MHz. The multi-stage design includes a gas discharge tube for maximum pulse energy protection. The DXE-RG5000HD rejects 10 watts of catastrophic receive antenna feedline RF while passing a maximum signal of about 87 dB over S-9, which is only 25 mw, a signal level that is well below the point of front end damage. Receiver Guards are a must for multiple radio contesting stations and they provide low-cost front-end "insurance." Use them in these common high-RF situations: - Receive antennas in very close proximity to transmit antennas - Field-day operations with many transmitters in close range - Multi-transmitter contesting sites - Neighboring Amateur and CB operators - Frequent high-power mobile encounters Extensively tested and proven in real-world stations, the Receiver Guard works for all radios and offers the ultimate performance required by the upper tier of transceivers tested to have the best narrow-spaced third-order dynamic range or published RMDR (Reciprocal Mixing Dynamic Range). These are passive electronic limiters, so competitive contesting stations use separate band filters in addition to the Receiver Guard. When there are high levels of RF on your receive antennas, the DX Engineering Receiver Guard generates far less harmonic noise than other limiters on the market, which allows your station to continue to operate safely and competitively. At normal HF signal levels the RG5000HD operates continuously with no effect on the performance of your station while providing the best possible protection for your radio. Here are key Receiver Guard features: * Keeps stray high levels of RF from damaging your receiver input * Ideal for separate 160 and/or 80 meter receive systems with large pulse and RF energy capture area * Uses state of the art components for maximum protection of receivers * Under 6 ns response time * Multi-Stage protection * Very low insertion loss * Uses BNC type connectors to avoid accidental connection to a transmit feedline * Has been developed and tested in world-recognized multi-multi contest station K3LR Specifications - DX Engineering Receiver Guard model DXE-RG-5000HD - Frequency Range: 0.5 through 150 MHz - Insertion Loss: < 0.15 dB up to 50 MHz, < 0.3 dB 50 MHz up to 150 MHz - VSWR: < 1.2:1 - Maximum Output Level at 10 W input: +14 dBm (0.025 W) - Maximum Power Handling: 10 W CCS (Continuous Commercial Service) - Device Impedance: 50 to 75 ohms, unbalanced - Connectors, Input and Output: BNC female Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. What happens if the receive antenna is extremely close to the transmit antenna, or there is an antenna support or other system failure that causes a high RF level to enter the receive antenna input?

DX Engineering Radial Plates

DX Engineering Radial Plates are made of 304 Stainless Steel, 1/8 inch thick and 11.625 in. x 11.625 in. outside dimensions. They are made with the finest Stainless Steel that will last! Not cheap aluminum that will dissolve in your soil! ".....it is so beautiful, I want to frame it and put it up on the wall - not in the dirt under my vertical. Sebastian - NS0W" Unique enough to be covered by two US Patents, (Pat. No. 6,927,740 and D533,167), the DX Engineering Radial Plate is meant for those of you that have or are building a quarter wave vertical antenna and who want an easy, neat and effective way to connect those essential radial wires and the coax to your vertical antenna for the lowest takeoff angle and strongest signals. Stainless steel construction assures that your signal won't disappear like a disintegrating aluminum radial plate. One OPTIONAL SADDLE CLAMP (SOLD SEPARATELY) IS REQUIRED to mount the DX Engineering Radial Plate to a ground mounted antenna support pipe, also sold separately. For STEEL pipe from 1 to 2 in. O.D. the all-Stainless Steel DXE-SSVC-2P is the REQUIRED clamp, sold separately. For STEEL pipe from 2 to 3 in. O.D. the all-Stainless Steel DXE-SSVC-3P is the REQUIRED clamp, sold separately. For pipe or rod whose O.D. is between 0.50 in. and 1.75 in. the DXE-CAVS-11P V-saddle clamp is the REQUIRED clamp, sold separately. For aluminum tubing from 1 in.to 2 in. O.D., the DXE-CAVS-2P V-saddle clamp is the REQUIRED clamp, sold separately. This plate will work perfectly with most commercially available vertical antennas such as the Hustler BTV series (4BTV thru the 6BTV), the SteppIR (BiggIR or SmallIR) or an antenna of your own construction. When used with the Hy-Gain AV-18HT Hy-Tower antenna, the radial plate will sit on the concrete under the base plate and will fit within the three concrete-mounted base/insulator pipes. The DX Engineering Radial Plate has a number of advantages over the other plates on the market: First, the DX Engineering Radial Plate will attach easily and rigidly to a 4x4 or 6x6 wooden post using simple wood screws, or to a steel or aluminum pipe (up to 3.0 in. outside diameter) using an OPTIONAL SADDLE CLAMP, SOLD SEPARATELY, to attach to whatever you have supporting your vertical. Size and clamp selection is detailed above. Second, this plate actually has a place where you can attach your coax! What a concept! The plate assembly has been drilled for optional SO-239 Chassis Mount and Bulkhead Fittings. This is a MUST item for proper handling of RF ground current! Regardless of how you do it, it is imperative that your coax be grounded to the radials to complete the circuit for your radial current. Third, the DX Engineering Radial Plate is laser cut from tough stainless steel so that it has smooth edges, won't corrode and will always look good. You will be proud of how good your installation looks. Fourth, it is square. Why? Because a square has more lineal distance around it than the round plates that you usually see. This allowed us to put 60 holes in it, use larger bolts for more clamping power and still not crowd them together. Remember: The more current that flows in through your radials and through this plate, the stronger your signal is going to be and the more DX stations that you are going to hear. So, put on as many radials as you can. Fifth, we supply the correct Stainless Steel bolts, nuts, star washers, flat washers and lock washers to attach the radials. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. For the absolutely finest made radial plate available, order DX Engineering Radial Plates. Suggested as a station upgrade product - make more contacts to worldwide DX stations and DXpeditions
