Description: Normal 0 false false false EN-US X-NONE X-NONE TACTICAL RADIO GEAR, LLCHF Multi-Band, 8-Band Bandpass FilterBPF-8 High Performance select-able Pass FilterAmateur Radio, Military HF, Commercial HF, and Marine Communications systemMade in the USA The BPF-8 features a Mother-Board, which functions as a Pallet, for up-to 8 plug-in filter modules. To keep the cost reasonable, and not burden the unit with unnecessary filters, the unit is priced with one filter module of your choice. Additional modules can be purchased as needed; for $35.00 and installed at any time. See the listing: BPF-8 BAND MODULE. The filter modules, feature the same circuit design as our mono-band BPF-200 series of filters.The BPF-8 is a compact 5-1/2" x 3-1/2" x 8" unit weighing <5 pounds. Its compact size, and light weight makes it ideal for portable field operations and for use with our Triplexer. The power requirements are 12VDC-14VDC @ 200mA Max. The BPF-8 is available with UHF or N type connectors.It comes standard, with a 6ft. DC power cable, 12vdc AC wall wort and a 2.1MM - 2.5MM adapter plug.Installation of the plug-in filter module(s) is easy and fast. Only 4 screws need to be removed, in-order to plug-in a filter module.The enclosure is a robust, anodized extruded aluminum extrusion. The overall design has been carefully thought out for both reliability and performance.The overall design, is essentially military type construction, and quality build. Outside of a better antenna, bandpass filters are the most important multi-radio station upgrade. The BPF-8 is designed to provide a sharp roll off just outside each Amateur band. Tactical Radio Gear, HF Band-Pass Filters are designed to restrict the transmit/receive pass-band to a single Amateur band. Additionally, they provide a much lower noise floor, necessary for weak signal reception; a must for DXers, contesting stations, and Field Day operations. These filters provide the extra isolation, necessary to allow multiple transceivers to operate on different bands simultaneously, using the same antenna. The BPF-8 Filters provide >40dB of out-of-band suppression, eliminating out of band noise and interfering signals. Typical insertion loss is <0.25dB with SWR >1.2:1. DEALERS WELCOME. NO MOQ, OR INVENTORY, WE DROP SHIP FOR YOU. WE ALSO PROVIDE AD-COPY AND IMAGES. HF Bandpass FiltersBandpass filters are essential, in preventing receiver front end damage during multiple HF radio operation. Tactical Radio filters are available for all HF amateur bands, including 6 & 2 meters. All models are supplied with UHF Female/SO-239 connectors; N-connectors can be substituted. Designed to provide a roll-off outside each Amateur band; these filters bring the benefit of a dramatically lower noise floor; for improved single-band, weak signal reception; necessary for contest and Field Day operations; or simply crowded band conditions! These compact HF Transmit/receive filters, accomplish out-of-band suppression, that effectively eliminates noise and interfering signals. Simply place the filter in-line between transceiver, antenna or an amplifier. If you are planning a DXpedition, a contest, or simply need the enhanced performance that a bandpass filter can provide, your radio needs these filters. Tactical Radio Gear, filters are the most cost-effective, single band filters on the market. The cutting-edge advantages, that these exceptional filters can provide; to improve image, and intrusive harmonic problems, for mono-band, multi-radio contest settings cannot be overstated. Tactical Radio Gear, filters are essential for use with transmit multiplexers, as these filters will augment the separation needed to tolerate multiple radios on different bands at the same time - on the same antenna. When used in combination with multiplexers; known as multi-band transmit combiners; it is essential for each multiplexer band to provide the additional isolation necessary to allow the operation of multiple transceivers; all transceivers in a particular situation, can operate in chorus, unhindered by the signals from radios operating on the other bands - or even on the same antenna. The Tactical Radio, BPF-8 filter design, is based on a 3-pole & 5-pole Butterworth filter configuration(s), that maintain a 50 Ohm impedance, and low insertion loss. These HF Transmit/receive Bandpass Filters, are of tremendously high-quality, and precisely designed to limit the RF bandpass to a single Amateur band. Inputs and outputs are not at DC ground potential. Hi-Q Precision Silver Mica capacitors, and heavy-duty inductors, are used in the L/C tuned circuits. Each filter is individually tuned on a state of the art testing system. Insertion: Typical, 0.5-.7db Rejection: Typical, >40db band-to-band Impedance (ohms): 50 RF Connector Type: UHF female, SO-239 or N - connector. Others type(s) available on request.Enclosure: Extruded aluminum VSWR & POWER CONSIDERATIONSHi VSWR will generate damaging RF voltages, and currents in a bandpass filter. VSWR is a reality that we have to be attentive to; and Tactical radio gear, has made every effort, to protect the filter components from these potentially damaging forces. These designs are over-engineered, with vigilant consideration to component selection. No expense was spared to insure the reliability and performance of our filters. The weak-link in most Bandpass filters; at these power levels, in a high VSWR condition, are the capacitors?. Tactical Radio Gear, uses High-Frequency, High-Power, High-Voltage, Silver Mica capacitors; ideal for use where multilayer ceramic caps are not recommended because of cracking. The natural mica dielectric retains its extremely high-Q to many megahertz; and is free from thermal cracking. Silver Mica capacitors are Ideal for tuned L/C Circuits & High RF current. Unlike NPO ceramic capacitors, these capacitors are rock stable - no change with time, V & f and a temperature Range of -55 C to +125 C. Individual capacitance Tolerance: ±5% @ 500 Vdc. While RoHS Compliant. All the inductors in our filters are wound with the largest possible gauge wire, consistent with sensible design practices. Depending on the band, the toroid cores when used, are selected for the largest gauge wire, and minimum turns, to minimize IR losses/heating. Not withstanding the robust design, operator(s) should endeavor to maintain a minimum VSWR when using these filters.Tactical Radio Gear, BPF-8 model filters, are designed for use with 100W/200W PEP transceivers. Note: The BPF-8 filter(s) can be operated @ a 100% duty cycle. SSB speech (50% duty), CW average power is roughly equivalent to speech. The BPF-8 has a by-pass feature, that takes the unit out of line.
