DX Engineering NCC-1 Receive Filter Sets
DX Engineering announces a series of NCC-1 Receive Filter Sets, a breakthrough option for owners of the NCC-1 Receive Antenna Phasing Unit. These advanced plug-in filter module sets offer frequency-specific receive antenna system enhancements for the NCC-1. All filter modules sets are available in matched pairs of 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 1 dB. Highly regarded by many owners and engineers to be the best receive phasing and noise canceling unit available, the DX Engineering NCC-1 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 NCC-1 Receive Filter Sets add a new dimension of functionality to the NCC-1, for advanced directional noise and signal nulling performance, enhanced with specific frequency range operations. By default, NCC-1 filter slots are jumpered to pass all signals. On the NCC-1 front panel, the BAND toggle switch "L" or "H" positions each activate one of two filter pair slots, allowing over 360 degrees of phase rotation in two frequency ranges. The BAND switch "L" position covers from 850 kHz to 8 MHz. The BAND switch "H" position covers from 2 MHz to 15 MHz. Frequencies outside these ranges will have less than 360 degrees of phase rotation. NCC-1 Receive Filter Sets must be placed into the proper BAND filter slots corresponding to desired usage. NCC-1 Receive Filter Sets are pairs of filters (2 of the same type), so both NCC-1 receive antenna inputs "A" and "B" exhibit the same pass-band characteristics. Band-pass, high-pass or low-pass filters are available for users to choose and install into their NCC-1 for their desired application. By reducing or excluding frequency-specific interfering noise and signals, the noise floor of the desired pass-band can be lowered for dramatically improved reception. You can install one set or two sets, depending on your desired filtering. NCC-1 "L" and "H" slots may be populated with pairs of band-pass, high-pass, or low-pass filters 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 NCC-1 Receive Filters, part number DXE-NCCFL-BPF80M, into their NCC-1 "L" BAND slots. This would dedicate their NCC-1 to 80 meter-only operations. Setting the BAND switch to "L" would dramatically reduce 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 on 80 meters could be achieved for dramatically enhanced reception of weak 80 meter DX signals. An additional pair of filters could be installed into the "H" BAND slots, to enhance reception on the higher HF bands. For example, installing 20 meter high pass filters, part number DXE-NCCFL-HP20M, and switching to BAND H would drastically reduce all received noise and signals from frequencies below 13.70 MHz. With advanced planning of additional filter availability, an NCC-1 owner could even swap different filter sets for optimal operations in different contests or band pursuits.

All NCC-1 Receive Filter Sets displayed here are also conveniently listed on a single page in the link tab called "Documentation." Order one or two DX Engineering NCC-1 Receive Filter Sets for your unit and enjoy the best possible performance from your NCC-1.

DX Engineering NCC-2 Receive Filter Sets
DX Engineering NCC-2 Receive Filter Sets provide an added dimension to the receive capabilities of the NCC-2 Receive Antenna Phasing System. These advanced plug-in filter module and adapter board pairs offer frequency-specific receive enhancements. The packages are available in pairs of high pass, band pass, and low pass frequency ranges with filter cut-off and center frequencies that correspond to the major Amateur low bands, 160, 80, 40 meters. Filter insertion loss is only about 1 dB. NCC-2 Receive Filter Sets are pairs of the original NCC-1 filters of the same type, each with the required RXFL-1 Filter Adapter. Both NCC-2 channels, "CH A RX ANT IN" and "CH B RX ANT IN" will benefit from the same pass-band characteristics. High pass, band pass, or low pass filter sets are available for users to choose and install into their NCC-2 for their desired application. By reducing or excluding frequency-specific interfering noise and signals, the noise floor of the desired passband can be dramatically lowered for greatly improved reception. Be aware that when filter pairs are installed, the NCC-2 no longer responds to signals out of the passband. In other words, at this time there is no electronically switched bypass for installed filters. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. The NCC-2 Receive Filters displayed here, and higher frequency band filters, are also available as single filters for the NCC-2, to create alternative wide-pass filter sets, and for DX Engineering single channel accessories, including the DXE-RPA-2, DXE-DMC-2 and the DXE RTR-2. The simplest way to filter your NCC-2 is to order one of these DX Engineering Receive Filter Sets for your unit and enjoy the best possible filtered performance from your DX Engineering NCC-2 Receive Antenna Phasing System.

DX Engineering Receive Filters
DX Engineering Receive Filters are available individually for use in the NCC-2, RPA-2, RTR-2 or DMC-2 with adapter boards. These filters are also available in sets with mounting fixtures for use in the NCC-1. DX Engineering Receive Filters are numbered for the key Amateur Band on which they function. The Band Pass filter models pass RF only on the numbered band, the High Pass models function on that band and all device frequencies above, and the Low Pass models work on that band and all device frequencies below. Response plots for Receive Filters are conveniently listed on a single page in this product's detail web page tab labeled "Charts and Guides". Some users will want to use a pair of these filters with two of the required DXE-RXFL-1 Filter Adapter Boards in their NCC-2. Each individual filter used requires a DXE-RXFL-1 Single Filter Adapter Board to convert them for installation in DX Engineering device models DXE-NCC-2, DXE-RPA-2, DXE-RTR-2 or DXE-DMC-2. All of the RXFL filters are still available in paired sets including two filters and one filter mounting fixture for owners of the legacy NCC-1 unit. See the Receive Filter Sets in combo packages by entering NCC-1 into the search box above.

DX Engineering Receive Short Element Active Vertical Antennas
DX Engineering Receive Short Element Active Vertical Antennas (the RSEAV Antennas) offer excellent low noise radio frequency reception from 40 kHz to 30 MHz. Better receiving performance than full-size transmit antennas and other active makes the DXE-RSEAV-1 the best choice on the market for VLF through HF reception, including long-distance AM broadcast, Medium Wave and Shortwave (SWL), and new low-frequency Amateur bands, DXing, contesting, and everyday HF operations. Click on a listed product title and Scroll Down to see additional important information. A complete product description appears below the Specifications Overview. Instruction manual links appear in the Documentation section. The sleek and stealthy DXE-RSEAV-1 includes a high-quality three-section 8.5 ft. (2.6m) aluminum tubing whip, insulated mounting plate and the completely new DXE-AVA-3 Active Matching Unit. Its state-of-the-art broadband operational amplifier design works as a high-impedance buffer between the short antenna element and RG6U 75-ohm coax. When installed in the appropriate location, RSEAV antennas provide significantly better weak signal reception than other active receive antennas and full-size transmit-capable antennas, with substantially reduced noise and lower spurious signal interference. Receive Short Element Active Vertical Antennas are intended to be mounted on a ground rod at ground level in a clear area away from all metal, towers and other antennas. They are sold individually (DXE-RSEAV-1), or with a bias tee (DXE-RSEAV-1FVI) and DXE-RSEAV-1 Receive Short Element Active Verticals set a new standard for "Active Receive Vertical Antennas" replacing legacy DXE-ARAV-3, ARAV-2, ARAV-1 and AL-24 versions. Use multiple DXE-RSEAV-1 for all 4 and 8 element DX Engineering Receive Arrays – all 3, 4 and 8 element Hi-Z Antennas Arrays – and 2 element receive arrays with DXE-NCC-2 and NCC-1 Variable Phasing Controllers. The DXE-RSEAV-1 is designed to be a very low-gain, low-noise antenna for greatly improved signal-to-noise performance over a very wide range of frequencies. In a proper single or multi-element array installation, this Receive Vertical antenna will attenuate high-angle skywave signals, which is the goal for a low band DXing receive antenna. Low-angle, long-range DX signals are easier to copy with a good radio and DX Engineering Receive Short Element Active Vertical Antennas. Please Note: To achieve the expected reception pattern, multi-element phased arrays depend upon identical gain and phase response from each element. Every individual element amplifier, its grounding, and even its feedline characteristics and length, must be identical to the others in the array. Therefore, when unrepairable failures occur, it is essential to replace or upgrade all the elements in the array with identical, fully compatible DXE-RSEAV-1 antennas or DXE-AVA-3 units.
