Airspy HF+ Discovery SDR Rx

Boni-Whip Active Antenna 20kHz - 300MHz Wide frequency range 20 kHz - 300 MHz Small dimensions  Ideal for traveling, at home or DX-Camps The BONI-WHIP active antenna replaces the very successful Mini-Whip antenna. Despite its size (only approx. 17 cm long), it renders excellent reception results on longwave, mediumwave and shortwave and additionally for VHF up to 300 MHz. We developed this antenna ourselves and it is built here in Germany, so it really is “Made in Germany” by Bonito. The antenna offers a lot of improvements and better values than the original Mini-Whip. In our newsroom you can see a benchmark test between the Boni-Whip vs. the Mini.Whip: http://newsroom.bonito.net Even on very low frequencies the Boni-Whip produces very good reception results. It can be used beginning with 20 kHz and is a good choice for listeners who are interested in low frequencies. We also thought about radio listeners who are interested in high frequencies and extended the range to 300 MHz. Even with only a little effort you can achieve fantastic reception results; and because of its small size, the antenna can be erected inconspicuously.  The active antenna circuitry is cased in a weather resistant box. The voltage supply is delivered by the antenna cable and the included power supply module.  Boni-Whip: As flexible as you Because of its interchangeable radiating elements (Whips) the Boni-Whip can be used with different elements for experiments. The antenna can thus be adjusted to the surrounding environment or a special reception area. Customer comment I have performed extensive outdoor tests on the Boni-Whip at various locations in Germany, Austria, and USA; and even I am amazed that we have produced an antenna with such small size, mobility and excellent performance/price ratio. You will get a noticeably better antenna for almost the same price as the original Mini-Whip. Boni-Whip: Quality made in Germany The electronics of the Boni-Whip are manufactured in Germany by an ISO9000-certified assembly company in industrial quality and assembled by us in the Bonito QTH. Technical data Boni-Whip Frequency range: 20 kHz -300 MHz Voltage supply: 12V-15V Gain: 3dB Upper Frequency Limit: (-1db): 300 MHz IP3: +32.5 dBm IP2: +55 dBm What's in the Box:  Boni-Whip active Antenna  Junction box  Whip / Radiator 5,5mm/2,1mm barrel DC power connector What else do i need? The Boni-Whip shortwave antenna is delivered without a coaxial cable, as everyone needs a different length. We offer you the right coaxial cables such as the H155 or the even better shielded Hyperflex 5 in different lengths. You need two coax cables: A coax cable between the Boni-Whip and the feeder with BNC plugs. In addition, another coaxial cable, from the feed switch (BNC plug) to your receiver. A stabilized 12V DC transformer power supply (no switching power supply!) Which can deliver approx. 150mA with a 5.5 / 2.1mm barrel connector is required for the power supply. The mast bracket, which is available in 28mm and 40mm, is useful for mounting on the mast etc. The OVP1000 surge arrester can also be useful for current weather events. To protect the BNC connector against weather influences, we offer a self-vulcanizing adhesive tape called NittoTape. If you want a little more amplification, you can also use the longer and flexible radiator, which brings approx 3 dB more level. Please note: The offered coaxial cables are custom-made and cannot be exchanged at a later date!Total length of the cable: cable cut +/- 3% + connector

This simple, lightweight travel loop is quick to deploy and the perfect companion for Airspy and similar SDR radios!   Most of the problems were related to ineffective RX antennas that were too sensitive to the surrounding noise. So we decided to design a new Noise Cancelling Passive Loop (NCPL) to fix the noise problem. The YouLoop is a generalization of the Möbius loop where a balanced electric shield is used as the centre of a multi-turn loop. The rest of the turns run inside the shield. To preserve this electric balance from alteration by the transmission line, a low loss miniature BALUN is used. The more turns, the higher gain at the lower frequencies. Note that to preserve the electric balance, the number of turns increases by increments of two. An aspect of this two-turns coax build is its response in VHF. The same HF magnetic loop can be used in the FM and the 2m HAM bands with a slight change of its core principle, it’s now a folded dipole. The feed point of the folded dipole is on the top and the actual legs are composed of the coax ground. In order to further improve the impedance matching and flatten the frequency response, a high impedance external pre-amplifier can be used near the antenna to present a constant output impedance to the receiver. This could be the best option for you if you do not want or cannot build the antenna from scratch. AS the only remaining action is to connect the SMA cables. Specification HF Response: 10kHz to 30 MHz VHF Response: up to 300 MHz Maximum Power: 250 mW No Tuning required Low-Loss Wide-Band BALUN with 0.28 dB loss typ.

BNC-SMA Adapter in premium Quality Many of the small entry-level SDRs such as SDRplay, Airspy, Airspy HF+ etc. as well as the high-quality Winradio, Elad FDM-S1 and FDM-S2 etc. have an SMA socket as an external antenna connector. This premium adapter, made of nickel-plated bronze, adapts a receiver or handheld radio with an SMA socket to a BNC socket. Quality you feel and hear You will immediately notice the high weight. This is because this adapter is made of nickel-plated bronze in premium quality. The PTFE dielectric ensures lowest insertion loss and a quiet frequency response.  Technical specifications Type: BNC female to SMA male Case: bronze, nickel plated Center pin: bronze with gold coating Frequency range: DC to 4GHz Dielectric: PTFE RoHS : Compliant

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, about 10-14cm long and SMA or BNC connectors. The result is impressive and works very well.
