Common-Mode Choke / RFI-Choke Standard 1 KW This common-mode choke prevents the shield of the coaxial cable from becoming part of the antenna system and radiating unintentionally. It also serves to match the unbalanced coaxial cable to balanced antennas and can therefore be used as a “1:1” balun.Built according to the W2DU principle, the 1 KW common-mode choke is extremely broadband and low-loss. A large number of high-permeability ferrites are threaded onto high-temperature-resistant PTFE coaxial cable, shrink-wrapped, and fitted with appropriate connectors. This makes it easy to integrate into the coaxial feed line.This Standard common-mode choke is approximately 45 cm long, very broadband, and provides about 1000 ohm of common-mode impedance in the frequency range from 80m to 2 m. It is weatherproof shrink-wrapped and has two high-quality PL259 connectors with PTFE dielectric and gold-plated contacts at the ends. A PL259 connector with PTFE and gold-plated contacts is included. Important Notice:When using an End Fed antenna, do not place the common-mode choke directly at the feed point of the antenna! A section of coaxial cable with a length of ≥ λ 0.05 (e.g., about 4.2 m on 80 m band) should be inserted between the End Fed transformer and the common-mode choke.Informationen gemäß Art. 19 GPSR Adresse des Herstellers: Bonito - Gerichtsweg 3 - 29320 Hermmansburg - anfragen@bonito.net- www.bonito.net Adresse der verantwortlichen Person: Bonito - Gerichtsweg 3 - 29320 Hermmansburg - anfragen@bonito.net- www.bonito.net
Galvanic Antenna Isolator GI1000 The GI1000 suppresses noise reaching the ground connections on the receiver. The GI1000 covers a wide-band range of 50 kHz - 1000 MHz (typ. 1db insertion loss). The unit can be used in many receiving applications, It will also work with frequencies up to 1,25 GHz but the insertion loss may increase by up to 3db. The unit also has integrated double over-voltage protection and input and output are blocked for DC voltage. The galvanic isolator GI 1000 separates the path of the direct current between the outer shield of the coax cable and the shielding of the antenna feeding line in order to suppress interference caused by potential differences. This is achieved by using a small toroidal transformer. The inner conductor of the coax cable is insulated with capacitors providing coarse and fine voltage surge protection. Specifications: Excellent protection against sheath waves and voltage surges.Double voltage surge protection. On the antenna side Gas Discharge tube with an ignition voltage of 90v. On the receiver side you will find an ESD-diode (30KV; max.pulse power 350W (8/20μs) Input and output has been blocked for direct currents of max. 50V. The GI 1000 is very useful for owners of a PERSEUS SDR who still own the original switching power supply. This little troublemaker has made life hard for many a PERSEUS owner. Caution: Only suitable for reception purposes, high RF performance (> + 10dBm) cause permanent damage!
CCMC30 Common Mode Noise Filter Noise filters are nothing new and are often used for transmitting purposes. They are used to prevent unwanted radiation via the coax shielding. It is less known that they can also suppress unwanted radiation when receiving signals, especially when an active antenna is used. However, in this case, the situation is reversed: en route to the antenna, unwanted interferences from electric home appliances can be effectively eliminated. NTi's Coaxial Common Mode Noise Filter (CCMC30) has been especially optimized for maximum common mode noise rejection of >30dB wide band in the frequency range of 150kHz - 30MHz. With slight limitations a much wider frequency range is covered. In the medium wave range for example a noise suppression of up to 45 dB can be achieved. This is possible by using a cascaded system of ferrite cores with various frequency dependent material properties, combined with high quality coaxial cable. For outdoor use, the system is housed in a water-proof enclosure. We recommend to connect the CCMC30 as closely as possible to the receiver.With regard to efficient noise suppression, the CCMC 30 is not very much different from the galvanic isolator GI1000. However, the CCMC30 performes down to lowest frequencies including DC voltage, in contrast to the GI1000, which blocks DC voltages and very low frequencies. The CCMC30 can thus be connected directly to the coax cable which passes the supply voltage or the control signals to the active antenna. A series connection of the GI1000 directly connected to the receiver followed by the CCMC30 right behind the power inserter may result in an even better performance. Technical Data Guaranteed frequency range: 150 kHz – 30 MHz Common Mode Wave suppression: >30 dB: 150 kHz -30MHz (>20 dB: 30kHz-60MHz) Insertion loss: <1 dB (up to max. 150 MHz) Size: 100x68x50mm (132mm with BNC connectors) Connectors: 2x BNC 50Ohms Weight: 320g Made in Germany
It’s great to reach a clean signal free of FM stations, broadcasts or whatever on modern equipments as ICOM IC7300. This filter is fully designed and manufactured from JG Hitechnology in Italy. Elliptical filter with 7 cells, low pass 0-74MHz. Brass cells separator manufactured especially for this filter. Each cell shielding allows great performances as the possibility to transmit up to 74 MHz and to have at the same time a strong attenuation at 88 MHz of 40 dB(at 98 MHz of 60dB, see graph below). It also allows to cancel FM residuals through all the HF spectrum up to 74 MHz. Usage range : Low pass filter with female/female SO239 connector. You can connect the filter directly between radio and antenna and use it in power with 120 watt. It’s ideal to break down FM residuals on HF (50 MHz and 70 MHz) frequencies for last generation radios like ICOM 7300 and similar. Low drop in reception up to 74 MHz. Uniqueness : Brass cells separator has been designed especially for this filter. 40dB attenuation at 88 MHz, >60 dB attenuation at 98 MHz. You can transmit up to 74 MHz with 100 W.

Technical features : 40dB attenuation at 88 MHz and 50 dB at 98 MHz Connectors SO239 Ceramic capacitors HI-Q RF 250V
Mini adapter cable Very short, flexible adapter cable made of Hyperflex 5 for short connections in top quality. The mini adapter cable is the ideal solution if you either want to connect two devices of different sizes or need a short, flexible coax connection. If you want to connect small SDRs like the Airspy HF+ with accessories like the GI300/or GI1000, there is often a problem: the BNC adapter and the GI300 or GI1000 are much bigger than the HF+ SDR receiver. Now you could use a regular adapter cable, but since the GI300/1000 separates the ground from the line, the cable must be as short as possible, but still flexible enough to bridge the height difference. Also, it is often not a good idea to plug the GI 1000 directly into a device, as the weight could damage the socket. This mini adapter cable consists of a short piece of Hyperflex 5 with SMA or BNC connectors. The result is impressive and works very well.

LP060 Low Pass Filter The elliptically-formed low pass filter LP060 from NTi suppresses all frequencies above 60 MHz. Highly effective antennas combined with near-by strong FM stations often overburden the input of the radio and cause interference and phantom signals. The LP060 was developed aiming at the highest possible suppression in the 88MHz - 108 MHz FM band, whereas as the 6m amateur radio band at 50MHz is still totally within the pass band. For the greatest possible effectiveness, the low pass filter should be inserted directly before the receiver input.

With the CCMC50 a reasonably priced version is now available with the following minor limitations against the CCMC30: Common mode noise rejection guaranteed> 30dB, broadband in the reception range from 500kHz - 50MHz instead of starting at 150kHz. Starting with the medium wave over short wave up to the 6m amateur radio band, which should be sufficient for most applications. Not suitable for outdoor use because it is not splashproof.

HP0020 High Pass Filter The elliptically-formed high pass filter HP0020 suppresses all frequencies below 2 MHz. Strong or near-by transmitters in the long- or medium wave range can cause interferences and intermodulation in the shortwave range, which can effectively be suppressed with this filter. The HP0020 filter is very steep, so that signals in the upper medium wave range are already suppressed effectively. For the greatest possible effectiveness, the low pass filter should be inserted directly before the receiver input. Attenuation values (typ.):<0.50 MHz:-55dB1.0MHz: -45dB1.6 MHz:-35dB2.0MHz: -3dB>2.5 MHz: -1dB Input and output are DC-blocked (max. 50V DC) Dimensons: 88mmx31mmx25mm (3,46 x 1,22 x 0,98 inch) Attention: Only suitable for reception, high HF (>10dbm) will cause permanent damage!
